Rory Blackwood dragged her trunk up the last stone step of Darkmoon Academy and told herself she would not set anything on fire today. She was fifteen. Her magic was six weeks old. In her pocket, folded small, was a page torn from her grandmother's journal, the word convergence bleeding through the paper. Nobody in her family had explained it before they died or lied or shipped her here. She had come to this gothic pile of towers to find out what she was. That was the whole plan. Luna Brightwell hit her at the door. Pink sweater, brown bangs, the smile Rory had missed for two years while her best friend was already learning to cast in these halls. "Roomies," Luna said. "I fought for it. Third floor, west side." "You didn't have to." "I did. You'd have picked a broom closet." Luna grabbed the handle of the trunk. "Come on. Orientation's in the long hall." The long hall smelled like cold stone and candle wax. Students clustered by school color. Rory kept her eyes down, drew a small sigil on her thumb with her nail, and felt the pressure in her chest step back one pace. That was when she noticed the boy. He stood across the hall, alone against a pillar. Uniform all black. Tie loose, sleeves rolled. Every shadow in the room leaned a little toward his feet like water tilting in a bowl. He was looking straight at her. Not glancing. Watching. "Who is that," Rory said. Luna followed her eyes. Her smile thinned. "Kael Evenmoor. Don't stare back. He doesn't do people." He was still watching. Rory felt heat gather under her collarbone. Her thumb-sigil went warm. A candle on the wall behind her hissed and doubled its flame. She crossed the hall before Luna could catch her sleeve. Kael did not move as she came. Up close he was taller than he'd looked, and his eyes were plain gray, not black. Not yet. "You've been staring at me since I walked in," Rory said. "Say it or stop." "You're loud." "Excuse me?" "Your magic. It's loud." He tipped his head half an inch toward the candle behind her, which was still guttering. "Everyone in this room can feel it. I'm the only one looking." Rory's jaw locked. "So you're what, warning me?" "Telling you." He paused. Chose the next words like coins. "Find me when you want to learn to be quiet." He pushed off the pillar and walked past her. The shadows unspooled from his feet and settled back into corners. Luna arrived at her elbow. "What did he say?" "He said I'm loud." Rory watched him go. Her hand was steady. The candle behind her had gone out. She had come here for one word in a dead woman's handwriting. She had just met the first person who'd heard her without being told.

The morning after the long hall, Rory sat between Luna and a bowl of cold porridge at breakfast. Kael was three tables over, alone, not looking at her. She thought about what he'd said. Loud. She drew a sigil on her wrist under the table and tried to make herself small. It didn't work. A girl behind her laughed too sharp, and Rory flinched, and the pressure in her chest kicked. The candles down the long table flared at once. Wax ran. A window latch snapped open. Every head turned. Across the hall, Kael stood up. The shadows under the tables slid toward him like spilled water. He walked out through the nearest door without looking back. Rory watched the space where he'd been and felt something cold open under her ribs. "Breathe," Luna said. She put her hand flat on Rory's back. Her voice was low and even. "In. Out. He's fine. He just doesn't want anyone reading him while you're doing that." "I'm not doing anything." "I know." Luna's smile was small now. "That's the problem. Rory. Everyone felt that." A prefect in a gray sash appeared at Rory's elbow before she could answer. "Blackwood. Headmistress. Now." Luna squeezed her wrist once. "Tell the truth. She likes the truth." The office was warm and quiet. Headmistress Aphrodite sat behind a desk of dark wood, blonde hair loose, robes stitched with silver marks Rory didn't recognize. She looked like a painting someone had forgotten to age. She didn't stand. "Sit." Rory sat. Her hands went into her lap. She waited for the part where she got sent home. "You blew out fourteen candles and a window latch," Aphrodite said. "Your roommate is worried. The Evenmoor boy left the room. Do you know why." "Because I'm loud." "Because you're unshielded." Aphrodite's eyes stayed on her. "I've felt you since the gate. You are the loudest thing in this building, including me. That is not a compliment. It is a problem I intend to solve." Rory's throat closed. "You're not expelling me." "No. I'm binding you." Aphrodite lifted one hand. A black cat stepped out from under the desk and up onto it, tail high, eyes bright green and gold. "This is Void. He has refused every witch in this school for six years. I brought him in this morning. He came to the door on his own." The cat crossed the desk and sat in front of Rory. He stared at her. She stared back. Her chest, for the first time since her birthday, went quiet. "A familiar takes the overflow," Aphrodite said. "He'll carry what you can't hold yet. In return, you feed him and you don't lie to him. Do you accept." Rory put out a hand. Void pressed his forehead into her palm. "Yes." "Good." Aphrodite's mouth almost moved. "Now we begin."

Three days after the binding, Rory hadn't slept. She'd missed her sigil class twice. She'd fallen asleep in herbalism with her cheek on a mortar. Void wouldn't let her rest. Every night the black cat sat by the door and stared until she got up and followed. Every night he led her the same way: down the east stair, past the kitchens, along a corridor that ended in a wing sealed with iron bars and dust. The left wing had been closed since before her mother was born. No one taught in it. No one talked about it. Void didn't care. He pressed his forehead to the bars and yowled once, low, and the pressure in Rory's chest kicked up like a struck match. A sconce down the hall flared. She jammed her palm against her sternum and dragged a sigil across her skin with a chewed pen. "You're doing it again," Luna said from the dark behind her. Her best friend stood in her pink robe with her arms crossed. "You went cold last night and I found frost on the window. Rory. Talk to me." "He wants in there." Rory nodded at Void. "When I don't go, I leak." "Then don't fight him alone." Luna's voice stayed flat and calm. "Ask the shadow boy. He owes you a lesson." Rory found Kael the next morning in the courtyard, alone at a stone bench, tie loose, sleeves shoved to the elbow. She said it fast before she could stop. "My familiar keeps dragging me to the left wing. If I don't go, I burn things. If I go, I hit a locked gate. Help me." Kael looked at Void. Void stared back. "Familiars don't pull without a reason." "Then help me open it." He stood. "Once. Tonight." At second bell Kael met her at the iron bars. He put one hand flat on the lock. His eyes went black. Every shadow in the corridor slid toward him and pooled at his wrist. The lock clicked. The gate opened an inch. Void shot through the gap. Rory followed. The pressure in her chest eased at once, clean, like a window opening. She almost laughed. Then Kael grabbed her sleeve. "Stop." The corridor beyond wasn't empty. Sigils were burned into every stone, floor to ceiling, and they were fresh. Someone had been keeping them lit. At the far end, chalked on the wall in a hand Rory knew from margins and old paper, was one word. Convergence. Her grandmother's writing. Here. Inside a wing sealed for decades. Behind them, footsteps. Measured. Unhurried. Headmistress Aphrodite stepped into the light with her hands folded, her face very still. "Out," Aphrodite said. "Both of you. Now." Rory didn't move. She stared at the word on the wall. Void wound around her ankles and did not look away from the Headmistress.

Aphrodite's office smelled of beeswax and old paper. Rory sat in a hard chair. Kael stood by the window, hands in his pockets. Void curled on the rug, tail flicking. A man in all black waited by the door, built like a soldier, no braid on his coat, no name given. The Headmistress folded her hands on the desk. "You went where you were not invited," Aphrodite said. "Twice, if I count the cat." Her eyes moved to Rory. "You will attend every class. You will sleep in your bed. You will not wander." She tipped her chin at the man by the door. "He will make sure of it. Ten paces behind. Always." "For how long?" Rory asked. "Until I decide otherwise." Kael's jaw shifted. He said nothing. Aphrodite's gaze cut to him. "You will keep to your own corridor, Mr. Evenmoor. Am I clear." "Clear," Kael said. By noon the Watcher was a shadow at ten paces. Rory counted them in sigil theory. She counted them down the stair to herbalism. She counted them at lunch, where Luna slid into the seat across from her and mouthed, *he's still there?* Rory nodded. Void sat on the bench beside her and watched the man watch her. She needed Kael. She needed to know what her grandmother had written on that wall and why. Every time she got near him in the hall, the Watcher's boots kept pace. Kael passed her at the library door and didn't look up. He passed her at the fountain. He passed her again outside potions and his fingers brushed hers, quick, and something small and folded pressed into her palm. *East cloister. Third pillar. After bell.* At the bell she walked the cloister slow. The Watcher followed. She turned the corner at the third pillar. A hand caught her wrist and pulled her sideways into a gap between stone and stone. Shadow closed over them like a shut door. She heard the Watcher's boots stop, then move on, then stop again, confused. Kael's shoulder pressed against hers. There was no room to stand any other way. His breath moved her hair. "Say it fast," he whispered. "The word on the wall. Convergence. My grandmother wrote it. What is it?" His eyes were black, holding the shadow around them. "It's not a place. It's an event. When two lines of power meet in one witch. The old covens killed for it. Yours knew." "Am I it?" "She thought so. So does Aphrodite." Her hand was on his chest. She hadn't put it there. He didn't move it. For one breath the corridor was only him. Outside, the Watcher's boots came back. Closer. "Go," Kael said. "Left, not right." She slipped out. The Watcher's eyes found her at once. He said, "You lost me." His hand rested on the hilt at his belt. "That won't happen again."

The note came at breakfast, folded under Rory's spoon. Aphrodite's handwriting. *After class. My office. Bring the cat.* The Watcher stood ten paces off, hand near his belt, exactly where he had been since the cloister. Rory pocketed the note. Void jumped onto the bench and pressed his shoulder against her arm. Aphrodite met her at the door in dark robes, sleeves already pushed back. "Private session. You are wasting the school's air with what you leak." She glanced past Rory at the Watcher. "Wait outside." He nodded once and took the wall. The Headmistress led her through a door Rory had not seen open before, down a stair, and out under trees. A small stone arch stood in the green, wrapped in vines. Lanterns burned inside. Void slipped through the arch first, tail high. "A grove," Aphrodite said. "Old. Quiet. It will hold what you spill." She made Rory sit on the moss. "Anger. Show me." Rory thought of the Watcher's boots. Heat rose in her palms. Aphrodite caught it in her own hand like a coin and closed her fingers. The heat went out. "Again. Smaller." They worked until Rory's hands stopped shaking before the flame came. Void watched from the step, eyes bright. They came back the next day. And the next. Aphrodite spoke in short orders. *Pull it in. Hold. Release.* Rory hated how well it worked. She hated more that Aphrodite smiled once, small, when a candle Rory lit did not blow the door off. On the fourth session Aphrodite stopped her mid-breath. "You are shielded enough. The Watcher comes off tonight." Rory looked up. "Off." "Off. You have earned the hall back. Do not make me regret it." Aphrodite's eyes held hers a beat too long. "I would rather reach you first than lose you to what waits outside these walls." By supper the corridor behind Rory was empty. Ten paces of nothing. She kept turning to check. Void wound between her ankles and would not let her stop walking. She found Luna in their room, cross-legged on the bed, brushing her long brown hair. Pink sweater, big smile, the one friend who had never once flinched at Rory's mood. Rory shut the door and sat on the floor. "She let me off the leash," Rory said. "She trained me in a grove. My hands do what I tell them now." Luna set the brush down. "And?" "And she wanted this. All of it. She's not scared of me anymore." Rory pulled her knees up. "Kael said Aphrodite thinks I'm the convergence. Why teach me to hold it steady unless she plans to use it?" Luna's smile went thin, but did not leave. "Then don't show her everything you can do. Keep one thing back. For us." Void jumped onto Rory's lap and settled. Rory nodded. The Watcher was gone. Aphrodite was closer.

Rory tore a strip from the back of her notebook at lunch. She wrote six words. *Grove. After dinner. Come alone.* She folded it twice and pressed it into Kael's palm when she passed his table. He did not look up. His fingers closed around the paper. That was enough. She ate fast, left Void curled on her pillow, and slipped out the side door while the halls were still loud. No boots behind her. The corridor stayed empty all the way down the stair Aphrodite had shown her. The stone arch stood dark against the trees. The lanterns were out. She lit one with a thought, small, the way she had been taught. Kael came through the arch a minute later. All black, tie loose, sleeves shoved to the elbow. He stopped inside the ring of light and looked at the door behind her, then at the trees. "No one followed you?" "No one. He's off me." "For now." He sat on the moss across from her. The shadows in the grove leaned toward him and he let them. Rory pulled her knees in. "I need the rest of it. Convergence. What it does to me. What she wants with it." "Two lines of power in one witch. I told you that." "You told me the name. Not what happens." Kael was quiet. A shadow slid up his wrist and he pushed it back down. "The lines fight for the same body. One wins. If neither does, the witch burns from the inside. Your grandmother wrote *not yet* because she was waiting for you to be old enough to survive it." Rory's hands went cold. "And Aphrodite?" "Aphrodite wants to be standing next to you when it happens. Whatever wins, she wants to hold the leash." Rory made herself breathe the way the Headmistress had taught her. In. Hold. Out. The lantern did not flare. "Why are you telling me this. Really." He looked at her. His eyes stayed his own. "Because you asked." "That's not an answer." "It's the one I have." "Kael." Her voice cracked on it. "I don't have anyone else who knows what I am. If that's all this is, tell me now." He did not move for a long second. Then he leaned forward and put his hand over hers on the moss. His palm was warm. He did not squeeze. He did not let go either. "It isn't all this is," he said. "But my court is coming apart. If they see me choose you, they use you to reach me. So I can't. Not out loud. Not yet." Rory turned her hand under his and held on. "Then not out loud." "Not out loud," he said. A branch cracked past the arch. Kael was on his feet before the sound stopped. Rory killed the lantern. Someone was already inside the trees, walking toward the grove.

Rory pulled her hand back from Kael's. He stood between her and the arch. The footsteps came closer, quick and light. Not a guard's stride. Rory knew that walk. "Rory Blackwood, I swear to every dark saint." Luna stepped into the grove in pink sneakers and a scowl that did not fit her face. Her bangs were damp from running. She stopped when she saw Kael. Her eyes went to the moss where Rory's knees had been, then to the space between them, then to Kael's rolled sleeves. "Oh," Luna said. "Oh." "Luna—" "You left Void on your pillow and slipped out the side door. I'm not stupid." She folded her arms. "Him. Really. Him." Kael did not answer. His eyes stayed on the trees behind her. "Was anyone with you." "No. I came alone because I thought she was going to burn a hedge down somewhere." Luna looked at Rory. "Talk. Now. Or I go back and tell the Headmistress you're missing." "You wouldn't." "I would. To keep you alive." Rory believed her. That was the problem. She looked at Kael. He gave one small nod. She turned back to Luna. "He's been helping me. Since the left wing. He's the one who told me what Convergence means." Luna's arms dropped. "How long." "Weeks." "Weeks." Luna sat down hard on the step. "You told him and not me." "I couldn't tell you. His court would use me to get to him. If anyone knew, they'd hurt him. They'd hurt me to hurt him." Rory's throat closed. "I wasn't hiding from you. I was hiding for him." Luna looked at Kael. "Is that true." "Yes," Kael said. "And the rest of it. The hand thing." Kael's jaw moved. "Also true." Luna took that in. She did not smile. She did not cry. She looked at Rory for a long second. "Okay," she said. "Okay?" "Okay. I'm in. But you tell me everything from now on. Every note. Every meeting. I cover for you or you both get caught." She pointed at Kael. "And you. If his court finds out through you, I will end you myself." "Understood," Kael said. Luna stood and brushed moss off her skirt. "Come on. Curfew's in twenty. We walk back together. If anyone asks, I found you crying about your grandmother and dragged you inside." Rory got to her feet. Her hands were shaking, but not from magic. Kael stepped back into the shadows past the arch. He was gone before Rory turned around. Luna took Rory's arm. Firm. Warm. "He's going to get you killed," she said, quiet. "I know." "I'm still helping." They walked back toward the academy together. Behind them, the grove went dark. Ahead, a lantern burned in a third-floor window that should have been empty. Someone was awake, and watching the path.

The lantern in the third-floor window stayed with Rory all the way to her room. Luna saw her looking and squeezed her arm harder. They passed the porter without a word. Void was waiting on the pillow. His bright eyes tracked Rory across the room. She did not speak until the door was shut and the bolt was thrown. "Someone was in that window," Rory said. "That wing's been empty since fall." "I know." Luna sat on the bed. "So we find out who. Tonight. Before they decide what to do with it." Rory pulled her grandmother's map of the academy from under the mattress. The third floor above the east path held four rooms. Three were storage. The fourth had been the old records office, locked since the roof leaked. She marked it with her thumb. "I'll go," Rory said. "We'll go." They took the servant stairs. Void followed three steps behind. On the third-floor landing the air smelled of dust and lamp oil. Fresh oil. Rory's stomach dropped. She drew a small sigil on her palm to hold her magic flat. The records office door stood open a finger's width. Light bled out. Rory pushed it. Headmistress Aphrodite sat at the desk inside. A lantern burned at her elbow. A cup of tea steamed beside it. She did not look surprised. "Close the door," Aphrodite said. Luna closed it. Rory stayed near the wall. Void slid past her ankles and jumped onto the desk like he had been called. "You watched us," Rory said. "I watched the grove. You went into it, and a boy followed. Then came out with her." Aphrodite's eyes moved to Luna and back. "I have not decided what to do about it." "Then why sit here waiting." "To hear what you say when you think I already know everything." Rory's hands went cold. The sigil on her palm itched. She thought of Kael in the shadows past the arch. She thought of Luna's promise on the step. She chose. "I met a boy in the grove," she said. "That's all you saw. I won't tell you his name and I won't meet him there again. Punish me for that if you want." Aphrodite studied her. The tea steamed between them. "A boy," Aphrodite said. "Fine. The grove is closed to you after dark. The east path also. If I see you on either again, I assign a Watcher for the term." She lifted the cup. "Go." On the stairs Luna waited until they were two flights down. "She let you lie." "She let me pick the lie." "That's worse." "I know." Rory looked at Void in her arms. His bright eyes stayed on the landing above. "She knows it's him. She's waiting to see what I do next." Luna nodded once. "Then we stop meeting where she can watch. We move the plan inside."

Luna took the first watch by the door that night. Rory left with Void at her heels and a folded note in her sleeve. The note named a place she and Kael had picked from her grandmother's map: a disused practice room behind the chapel wing, buried under years of dust. No windows. One door. Nothing Aphrodite could keep an eye on. Kael was already inside when she pushed the door shut. He sat on the edge of an old worktable, sleeves rolled, a single candle burning between them. Every shadow in the room leaned toward him. Void jumped up beside the candle and settled. "Show me what you brought," he said. She spread the map on the table. She had marked the sealed left wing, the third-floor office, the grove. She had drawn a line between them. "Three points," she said. "They form a triangle over the old chapel foundation. If Convergence needs a place, that's the place." Kael studied the line. "Then we go under. Not through the gate. Under." "How." "Shadow. I can hold a way open for a few minutes. Not longer." "When." "The night she stops watching. We'll know." Rory nodded. She rolled the map. Her hands would not stop moving. She reached for the candle to pinch it out and Kael caught her wrist. "Stop," he said. She pulled back on habit. He let go on habit. Then he didn't look away. "I need to say a thing," he said. "Once." Her stomach dropped. She reached for the shrug, the flat mouth, the bored eyes. All of it was right there. "Say it," she said. It came out sharp. It came out wrong. "I've never wanted to be near a person," he said. "I want to be near you. I don't know what to do with it." He stopped. He had said he would. Rory felt the armor lock into place. The smirk. The turn of the shoulder. The line already forming in her mouth about how he shouldn't say things like that in a room with one door. She didn't say it. She looked at him and let her face go. It cost more than the sigils cost. Her eyes filled and she did not wipe them. "I felt it in the hall," she said. "The first day. I've felt it every time since. I didn't tell you because I was scared you'd stop if I did." He didn't move for a second. Then he put his hand flat on the table between them, palm up. She put hers on top of it. Void's bright eyes watched them both. "Okay," Kael said. "Okay," she said. They stayed like that until the candle guttered. Then they made a plan for the night Aphrodite looked away. The night where there would be a full lunar eclipse. Rory walked back to her room with the map in her sleeve and something new under her ribs. It felt like a target. She kept it anyway.

The eclipse was set. Rory spent the weeks before it drilling her sigils until her fingers cramped. She showed Aphrodite the clean version of her magic in the grove: fire she could pinch out, a chill she could pull back. What she never showed anyone was the other thing. The part that came up under the pretty part. The part that killed the yard on her birthday before it grew back doubled. It felt like a second mouth behind her ribs, and it opened when she got scared. Luna sat on the floor of their room the night of the eclipse, braiding a red thread around Rory's wrist. She tied it off and did not let go. "You're going to lie to him down there," Luna said. "Aren't you." "I don't lie to him." "You hide. Same thing under a foundation." Luna finally let go. "He's opening a hole in the world for you. If it collapses because you didn't tell him what you actually carry, that's on you." Rory looked at the cat curled on her pillow. Void watched her back with those bright eyes and did not blink. "He'll stop," Rory said. "If he sees it." "Then he stops," Luna said. "Better than buried." The chapel room was cold. Kael was already crouched at the flagstones, palm flat. Shadows pooled at his wrist like water. His eyes were fully black. "Ready," he said. "Wait." He looked up. The black held. "There's a thing I do," she said. Her throat closed. She forced it. "Under the fire. Under the cold. It kills first. Then it makes more. I don't know how to stop it once it starts. If I panic down there, it will come up." He watched her. He did not move. "Show me," he said. She held out her hand over the candle. She let the second mouth open a crack. The flame went black and thin. The wax under it curdled. A dead smell lifted off the table. She shut it again fast. Her hand shook. Kael did not flinch. He took her shaking hand and pressed it flat against his chest, over his heart. His skin was warm through the black shirt. "Okay," he said. "Okay?" "I can hold shadow around it. If it comes up, feed it to me. Don't hide it. Look at me and feed it to me." She nodded. She was crying and did not wipe it. He leaned down and kissed her. It was short and steady, like in the ways he spoke. His mouth was warm. Her second mouth stayed shut. He pulled back. The flagstone under his hand dropped away into black. A passage yawned open under the old foundation. Cold air came up from it. "Now," he said. Rory picked up Void, tucked him under her arm, and stepped down into the dark with Kael's hand in hers.

The passage under the chapel foundation dropped them into cold stone. Rory's boots skidded on wet grit. Kael landed beside her without a sound. The shadow he'd cut into the floor above closed to a thin seam of gray. Void jumped down from her arm and stood at her ankle, tail up, eyes bright in the dark. "Twelve minutes," Kael said. "Then the passage seals." She nodded. The walls were older than the academy above them. Sigils crawled across the stone, some fresh, some scratched over by newer ones. Her grandmother's hand was in there. Rory could feel it like a hand on her back. They walked. The corridor narrowed. The second mouth behind her ribs flexed once and settled. She kept walking. She had rehearsed this. Find the center. See what Convergence was. Get out. Don't die. What she had not rehearsed was the sentence in her mouth. At the end of the corridor a low arch opened into a round room. Two grooves cut the floor and met at a point in the center. Two lines. One witch. She stopped at the edge. "Kael." He turned. His eyes were still full black from holding the passage. The shadows around his feet leaned toward him. "I need to say a thing before we go in." "Say it." She had waited eleven weeks. She had hidden behind sigils and cover stories and Luna's red thread. Her throat closed the way it always closed. She forced it open. "I want you," she said. "Not the help. Not the shadow. You. After this. Whatever's left of me after this, I want it to be next to you." His face did not move. The black in his eyes held. For a second she thought he had not heard her, or had heard her and decided nothing. Then he stepped in and put his forehead against hers. His hand went flat on the back of her neck. Warm through the cold. "Yes," he said. One word. He did not soften it. He did not explain it twice. She breathed out. The second mouth under her ribs did not open. Something else did. A small clean space where a wall had been. Void walked past them into the round room. He sat on the point where the two grooves met and looked back at her. Waiting. Kael's hand slid down and took hers. "Now they'll use it," he said. Flat. Honest. "If anyone hears. My court. Aphrodite. Anyone." "I know." "Still?" "Still." She stepped over the threshold with him. The grooves in the floor lit under her boots, thin and white, running toward the cat. Somewhere above them, in the academy's gothic spires, a bell started to ring that should not have been ringing. Kael's grip tightened. "They know we're down here," he said.

The bell above kept ringing. Rory stood on the lit grooves with Kael's hand in hers. Void sat at the center point, tail curled tight. The chamber answered her. Not in words. In a warm push against the inside of her chest, like someone leaning on a door from the other side. She froze. The push felt like Kael. It also did not feel like Kael. Two things at once. "Something's in here with us," she said. "Something that isn't you." Kael's black eyes swept the room. "Say more." "It's answering me. When I think, it thinks back." Her voice shook. "If I open to the wrong one, I open to the wrong one forever." She pulled her hand back from him. Just an inch. Just enough to test. The push in her chest stayed. It was not coming from him. Void meowed once, sharp, and looked past her shoulder. Rory turned. Her grandmother stood in the archway. Translucent, thinner than the last dream, her white hair moving in air that wasn't moving. The pendant at her throat caught the groove-light. She looked tired. She looked like she had been running. "Grandma." "Little bird." Ada stepped onto the grooves and did not disturb them. "Listen. I have one minute of me left in here." Rory's throat locked. "The thing answering me—" "Is the chamber. Is him. Is you. All of it." Ada's mouth pressed thin. "Convergence isn't a thing done to you, Rory. Two lines. One witch. That was the old lie. It's two witches. One line. You and the shadow boy. Yin. Yang. Balance. Together you are the convergence, or neither of you is." Kael went still beside her. "The bell," Rory said. "They're coming." "Then we shut the bell." Ada raised her thin hand and knocked on the air. Three. Pause. Two. "The pattern I taught you at four. In the cedar song. Do you remember?" Rory did. Her hand moved before her head caught up. Three. Pause. Two. She knocked on nothing. The bell above them cut off mid-swing. The academy went quiet over their heads. "Good girl." Ada was already fainter. "Now the harder thing. If you want him, you merge here, tonight, on the point. Not later. Later, she takes one of you." "She?" Rory said. "Aphrodite?" Ada did not answer that. Her sentences got shorter when she was firm. "Stand on the point. Hand in his hand. Say yes out loud. Once each." Rory looked at Kael. His black eyes held on her face. He did not ask what she wanted. He already knew. They stepped to Void together. The grooves burned white up her boots. Her chest opened wide and clean. It was him. Only him. She had her answer. "Yes," she said. "Yes," Kael said. Ada was gone. The chamber closed around the two of them like a held breath.

The chamber held its breath. Then Rory felt it — a warm line running from her sternum to Kael's, thin as thread, real as bone. Her feet left the floor. His did too. The grooves under them poured white light up their legs. She rose a foot, then two, then hung there with him in the middle of the round chamber, hair drifting like she was underwater. Kael's black eyes stayed on her face. His hand did not let go. Her walls fell. Not slow. All at once. Every guarded room she kept inside her head opened its doors to him, and his opened to her. She felt his tired court in his chest. He felt the burn she carried under her ribs. Nothing hurt. That was the strange part. She had built those walls for fifteen years. They came down like paper. Ada flickered back at the edge of the grooves, thinner than before, barely a shape. "Little bird. Listen quick." Her voice was small. "She will be at the top of the stairs. She will ask you what you did. You tell her nothing. You climb out and you climb out together." "Grandma —" "Something is collecting bright ones. She works for it or she is it. I don't know yet." Ada's mouth firmed. "When she reaches, use the knock. Three. Pause. Two. It turns her away for a breath. A breath is enough." "What about Luna?" Ada's face softened. "Tell her plain. She loves you plain. She'll hold." Ada thinned to nothing. The light in the grooves eased. Rory's boots touched stone. Kael steadied her by the elbow. The black cat wove once around her ankles, bright eyes lifted, then trotted toward the passage as if he already knew the clock. "Twelve minutes is gone," Kael said. "We have what's left of the shadow." "Then we go." They ran. The passage narrowed as his magic pulled it closed behind them. She felt him feel her fear and steady it. She felt her own steady his. One nervous system now, sharing the load. They came up under the chapel foundation. Rory climbed the last stones and pushed the slab aside. Headmistress Aphrodite stood at the top of the stairs. Beautiful. Still. Waiting. "Rory," she said. "What did you do down there." Rory did not answer. She raised her hand and knocked on the air. Three. Pause. Two. Aphrodite's head turned a quarter inch, as if she had heard someone call from another hall. Her eyes lost Rory for one full second. Rory and Kael walked past her, shoulders touching, the cat between their feet. At the end of the corridor, Luna stood in the doorway in her pink robe, arms crossed, jaw tight. "Tell me," Luna said. Rory did not slow down. "I'm merged with him. It's done." Luna's smile did not come. But she stepped aside and let them through.
