Scarlett Hayes had one plan today: reach the boy she loved before she lost her nerve. She'd rehearsed the words for a week. Now the tide had eaten the path. Brown water slid over the low stone walk of Quietmoss, swallowing the stepping stones one by one. On the far side stood his house. Between her and it, the flood widened by the minute. She paced the wet edge, red hair sticking to her cheeks. Her blue top and short maroon skirt did nothing against the spray. The water was too deep to wade and too fast to trust. Every plan she made, the tide beat. "You're thinking so loud I heard you from the trees," a voice called. Azumi Sakamoto dropped out of the air and landed on the wet stone. Her feet barely touched down. Scarlett's best friend could fly, and she never let anyone forget it. She wore even less than Scarlett, a tiny green top and a plaid skirt slung low, and she grinned like the flood was a gift. "You want to cross," Azumi said. She tapped Scarlett's forehead. "To see him. I can hear it, you know. Loud and mushy." Scarlett shoved her hand away, face burning. "Then help instead of reading me." "I can carry you." Azumi lifted an inch off the ground to prove it. "But not far. You're heavier than you think." Scarlett looked at the water again. Something bumped the bank near her boots. A long board floated there, carved all over with strange dark spirals and shapes that seemed to watch her. It had come loose in the flood. She grabbed it before it drifted off. "A paddle board," she said. "I paddle, you push and guide. We stay low." Azumi clapped. "Yes. Bad idea. Love those." Scarlett flopped onto the strange board. The carvings felt cold under her palms. Azumi gripped the back and rose just enough to shove them off the stone. The current caught them at once and spun them sideways. Scarlett dug her hands in and pulled. Water soaked her to the ribs. "Left, left!" Azumi shouted, hauling the tail straight. They slid past a drowned bench and a floating basket. Halfway across, the board tipped. Scarlett threw her weight flat and held on. Azumi pushed harder, gasping now, her flying weaker over the deep water. The board struck the far steps hard. Scarlett scrambled up onto dry stone, chest heaving, alive and across. She'd made it. But his door hung open. The house was dark and empty. Wet footprints led away from it, toward the high ground, gone before the flood. He had already left. Azumi landed beside her and read it off her face. "He's not here." Scarlett stared at the muddy prints climbing the hill. She had crossed the impossible water and reached the wrong side of the day. Now she had to find where he'd run.

Scarlett followed the muddy prints uphill until her legs shook. The wind cut through her wet top and skirt. Her teeth chattered so hard she couldn't speak. She stopped and hugged herself. The footprints climbed on, but she couldn't. Cold beat her worse than the flood had. "You're blue," Azumi said, landing beside her. "Not a good look. We stop." "He's g-getting away," Scarlett stammered. "You chase him like this, you fall down dead. Then he marries someone warm." Azumi grabbed her wrist and pulled. "Come on. Trust me." Azumi flew ahead, low over the ground, and found a dark cave mouth ringed with green moss. Purple stones glowed inside, throwing soft light on the rock. Warmth breathed out of the opening. Scarlett stumbled in and dropped beside the biggest crystals. They were hot to the touch, like stones left in the sun. "Told you." Azumi flopped down next to her and pressed close. "I heard the cave before I saw it. Warm thoughts. Like a nap made of rocks." Scarlett curled against the glowing stones. Azumi wrapped an arm around her and shared her heat. Slowly the shaking stopped. Feeling came back to Scarlett's fingers. She flexed them and almost cried from relief. "Better?" Azumi asked. "Better," Scarlett breathed. Her clothes steamed in the purple light. She looked at her friend, half naked and grinning, holding her without a second thought. "You didn't have to stop for me." "Yeah I did." Azumi tapped Scarlett's forehead. "Your thoughts got quiet. Scared me." While they dried, Azumi gathered fallen branches from the cave floor. She stacked them and struck a glowing stone against dry moss. A small fire caught, and its flames sparkled strange colors, pink and gold. The warmth doubled. Scarlett spread her skirt to dry and let the heat sink into her bones. Then she saw them. On the cave wall, past the fire, dry footprints. Muddy tracks led in from the mouth and stopped at a flat stone shelf. Someone had sheltered here before her. Recently. Scarlett crawled to the shelf. A cup sat there, still holding water. A blanket lay folded beside it, warm from the stones. She pressed her palm to the blanket. Someone had left it minutes ago. "Azumi." Her voice sharpened. "He was here. In this cave." Azumi closed her eyes, listening for stray thoughts. She frowned. "Someone scared. Ran when he heard us coming up the hill." She pointed past the fire, to a second opening at the cave's back. "That way." Scarlett stood. Her legs held now. Warm, dry, steady. She snatched the blanket and wrapped it tight. The cave that saved her had hidden him too. He'd fled again, but this time only moments ahead. She could catch him now. She stepped toward the dark back passage, into the deeper dark.

Scarlett took one step into the back passage. Then she heard water. It hissed behind her, cold and fast. She turned. The flood had climbed the hill. It poured through the cave mouth and spread across the floor. It swallowed the fire in a puff of steam. The purple stones dimmed under the rising dark. The way back was closing. "Azumi!" Scarlett spun toward the fire pit. Her friend lay curled beside the last warm stone. The heat had pulled her under. She slept, one arm flung out, mouth open. The water crept toward her hair. Scarlett looked at the black passage. He was minutes ahead. If she ran now, she might catch him. She looked at Azumi. The water touched the sleeping girl's shoulder. The choice took no time at all. Scarlett dropped the blanket and splashed back. "Wake up!" She grabbed Azumi's arm and pulled. "Flood's inside! Fly, Azumi, fly now!" Azumi's eyes cracked open. She saw the water, then she saw Scarlett's face. She read the fear in it before Scarlett said another word. "You came back," Azumi mumbled. "For me." "Of course I did! Move!" Azumi rose off the floor, dripping and dazed. She lifted a foot clear of the water and blinked hard. "He got away, then." "I don't care. Go up. The passage." Scarlett shoved her friend toward the dark opening at the cave's back. The front was gone now. Only that one way led higher. Azumi flew ahead through the passage. Scarlett waded after her, the water at her knees, her waist, cold biting deep again. The passage sloped up. She climbed. The flood chased her but the floor rose faster. Slowly the water fell behind. They came out onto a ledge above the tide. Scarlett dropped onto stone and gasped. Azumi landed beside her and hugged her hard. "That was dumb," Azumi said into her shoulder. "You had him. You let him go for me." "You'd have drowned." "Yeah." Azumi pulled back and grinned, wide and shaky. "So now you're stuck with me." Then her grin faded. She tilted her head, listening. "He's still up there. Scared thoughts. Close." Scarlett looked past the ledge. A carved stone sat in the moss, dark and wet, covered in strange curling marks. Water striations ran through it. She had never seen writing like that. Muddy fingerprints smeared one edge. He had touched it, right here, and run. "He dropped something." Scarlett crawled to the stone and pressed her palm to the marks. They were warm. "Or he left it for someone." Azumi crouched beside her and frowned at the runes. "I can't read those. But whoever carved them wasn't from around here." Scarlett stared at the twisting lines. She had lost the boy for now. But the trail had turned into something bigger than one runaway. She wrapped her arms around herself and stood. "Then we follow the stone," she said.

Scarlett knelt by the carved stone and pressed both hands to the runes. The marks glowed under her palms. She meant only to feel the shape of them. But the light flared, and the ledge shook. "Scarlett, let go!" Azumi grabbed her wrist, but the stone held Scarlett's hands fast. Blue hair whipped across Azumi's face. She yanked hard, feet lifting off the rock, all her flying strength in the pull. Scarlett tore free and fell backward. The wall behind the stone split open. Water burst through the crack. Not a trickle. A wall of it, roaring down from somewhere higher, framed by glowing purple crystals set in the black rock. The runes on the arch above the falls lit one by one, purple and bright. "It made a waterfall," Azumi shouted. "Out of a wall! How does that even happen?" Scarlett scrambled up. The water pounded the ledge and pooled fast around her ankles. The dry stone was shrinking. There was no route off the ledge now, only the falls and the drop behind them. "The stone did this." Scarlett wiped spray from her eyes. "I touched it wrong. I woke it up." Azumi hovered above the rising pool, reaching down. "Then stop touching things! Grab my hands!" Scarlett looked at the crashing water. Something moved behind it. A dark shape, curled and huge, pressed against the sheet of white. She could not tell if it breathed or if the water only made it seem alive. Fear ran cold down her back. But under the fear, she felt something else. The runes had answered her hands. This place knew the boy she chased. He had touched a stone like this one. The trail did not end at the ledge. It ran through the falls. "There's a way behind the water," Scarlett said. "He went through something like this. I know it." "You want to swim into that?" Azumi's voice cracked. "There's a thing in there!" "I want to not drown here." Scarlett grabbed Azumi's outstretched hands. "Lift me over the pool. Set me on the ledge beside the falls, where the crystals are." Azumi's grip tightened. She read Scarlett's face and stopped arguing. She flew backward, dragging Scarlett across the flooding rock. Her sneakers skimmed the water. She dropped Scarlett on a narrow shelf of glowing stone at the edge of the falls, then landed beside her, panting. "You're stuck with me, remember," Azumi said. "So we go together." The pool swallowed the last of the dry ledge behind them. There was only the shelf, the roaring water, and the dark shape waiting inside it. Scarlett gripped a purple crystal and leaned toward the gap where the falls met the wall. "Together," she said. "On three." The trail had opened a new door. It led straight into the water, and into whatever lived there.

They went through on three. The falls hit like ice fists, then let them fall onto wet rock behind the water. Scarlett coughed and wiped her eyes. They stood in a small cavern lit by purple crystals. A carved stone waited on the wall ahead, marked with the same runes that had trapped them. More of the falls, a second set, blocked the only way forward. Azumi hovered close, dripping. "Please don't touch that one." "I have to." Scarlett studied the marks. They spiraled inward, like water down a drain, with a curled shape carved at the center. "The first stone flooded us because I read it wrong. I pressed all the runes. But look. They go in an order. Center last." "You're guessing." "I'm reading." Scarlett's hands shook. One wrong touch and both falls would seal the cavern. They would drown between two walls of water. She traced the outer spiral without touching. "The boy came through here. He didn't die. So there's a safe path." A new voice cut through the roar. "There is. You just found half of it." Scarlett spun. From a crack in the black rock climbed a woman with a spider's lower body, eight dark legs folding neat beneath her as she settled. Her purple eyes fixed on Scarlett with cool patience. She moved like she owned the stone. "Who are you?" Scarlett said, backing toward Azumi. "I keep the crossings." The spider-woman tilted her head at the runed stone. "Press the spiral inward, one mark at a time. Skip a step and the walls close. The boy pressed them slow. Most who rush end up part of the water." Azumi read her face and grabbed Scarlett's arm. "She's not lying. I can feel it. She's bored, not cruel." Scarlett looked back at the stone. She could wait and hope, or trust a stranger with eight legs. She chose. She pressed the first outer rune. It glowed soft green, not the harsh flare from before. Her breath caught. She pressed the next. Then the next, working slow around the spiral. Each one warmed under her finger. "Center last," the spider-woman said. Scarlett touched the curled shape at the heart of the stone. The runes flared once. The second falls parted like a curtain pulled aside. Behind it hung a great wooden bridge, dark timber and iron chains, lowered across a black gap. Solid ground. A real crossing. Azumi whooped and spun in the air. "You did it! You actually read it!" Scarlett let out a shaky laugh. Her legs felt like water. She had learned the stones. The trail led over the bridge now, and she could follow it without drowning. The spider-woman started back toward her crack. "The bridge leads to where your boy went. But he was not running from nothing." She paused. "He was running from what waits on the far side. You'll want me with you."

The bridge waited past the parted falls, dark timber and iron chains lowered over a black gap. But Azumi did not move toward it. She floated backward, hugging her arms, blue hair dripping. The spider-woman's warning had lodged in her like a splinter. Running from what waits on the far side. Azumi could read minds, and Scarlett watched her friend read something in the dark that she did not like. "I'm not going," Azumi said. "Whatever's over there, she felt it. I felt her feel it." She jabbed a finger at Arachne, who crouched patient by her crack in the rock, eight legs folded neat. "You want us to walk into that." "I keep the crossings," Arachne said, cool. "I don't push anyone across. The boy went. You can turn back and drown in the flood behind you. Your choice." That was not helping. Scarlett flew to Azumi and took both her wet hands. "Look at me. Not at the dark. Me." Azumi's eyes were wide, her breath quick. "I hear it, Scar. Something big. Something old." "I know. And I'm scared too." Scarlett squeezed harder. "But he's over there. The boy I crossed a whole flood for. I paddled a board, I froze half to death, I read those stupid runes. I'm not stopping ten feet from him." Her voice cracked. "And I'm not going without you. You pushed my board across the water. You saved me in the cave. I need my best friend on that bridge, not behind me." Azumi's chin trembled. She glanced at the black gap, then back at Scarlett's face. Whatever she read there steadied her. "You really love this boy." "So much it's dumb." A short laugh broke through Azumi's fear. She wiped her eyes with the back of her wrist. "Fine. But I fly ahead. If it moves, I drop you and run." "Deal." Arachne uncoiled and stepped onto the bridge first. Her legs found the timber sure and quick. "Good. Fear passes. Grab what's under it." She nodded at the far end, where something leaned in shadow against the last post. A sword. Its blade held a faint purple glow, and green tentacles curled around the hilt like a carved fist. "The boy left that. He couldn't carry it and run. You'll want it before you meet what he ran from." Scarlett's stomach dropped. She had thought she was chasing a scared runaway. Now a strange guardian talked about weapons and things that waited, and her boy had dropped a glowing blade to flee faster. Azumi rose over the chains, steadier now, teeth set. "Come on, then. Before I change my mind." They started across. Scarlett kept her eyes on the glowing sword at the bridge's end. She had won her friend back to the pursuit. But the reward waiting for her wasn't the boy. It was whatever he'd been too afraid to hold.

Scarlett stopped three steps from the sword. It leaned against the last post, its purple blade glowing, green tentacles curling around the hilt. To reach it she had to step past the shadow of the post, into the open. And in that open space, something waited. She had seen the dark shape shift beyond the far end of the bridge. The boy had dropped this blade and run from it. Now she had to walk toward it. "I'll get it," Azumi whispered. "I fly faster." "No." Scarlett caught her wrist. "You said you'd drop me and run. I'm not sending you first." Her heart slammed. But Azumi's hand was warm, and that steadied her more than anything. Next to her friend, the fear shrank to a size she could carry. Arachne crouched by the far post, eight legs folded, her purple eyes calm. The spider-woman had guided them across the falls and onto this bridge. Scarlett trusted her, even now. "The thing beyond," Scarlett said. "Will it move if I grab the sword?" "It moves when you're weak," Arachne said. "Go together. It fears bonded things." Scarlett looked at Azumi. "Bonded things. That's us." Azumi laughed, shaky. "Dumbest team ever." They went together. Azumi hovered close, one hand on Scarlett's shoulder. Scarlett walked into the open. The dark shape at the bridge's end swelled. A low growl rolled across the timber. Scarlett kept moving. She reached the post. She wrapped both hands around the tentacled hilt and lifted. The sword came free. Purple light flared up the blade and washed over the bridge. The growling stopped. From the shadow, a creature stepped into the glow. It was not the monster she feared. It was a striped beast, dog-shaped, with wide bat wings folded on its back. Its blue eyes fixed on Scarlett. It did not attack. It watched her, solemn, as if weighing what lived inside her. "It's reading you," Azumi breathed. "Not your mind. Your heart." Scarlett stood still, the glowing sword raised. She thought of the boy, of crossing the flood, of everything she'd risked to reach him. Then at the last second she thought of Azumi. The winged beast tilted its head. Then it lowered its front legs, a slow bow, and stepped aside. The path past the bridge lay open. "It let us through," Scarlett said. Her voice cracked with relief. Arachne rose. "It guards this crossing too. It bowed to what it found in you." She looked at the blade. "You carry that now. The boy couldn't. You can." Scarlett gripped the hilt tighter. She had the sword. She had passed the test the boy had failed. But the winged beast's bow told her something colder. The blade was not a prize. It was a burden meant for whoever chased the boy to the end. Beyond the bridge, the trail waited, and now she carried the thing he'd been too afraid to hold. She also holds an understanding in her heart of who she truly loves.

The winged beast stepped aside, and the path past the bridge lay open. Scarlett lowered the glowing sword. Her arms shook. The beast had bowed to her love for Azumi, but Azumi didn't know that love had a name. Scarlett had risked a flood, a cave, a waterfall, and a monster to reach a boy. Now she stood on the far side of everything, holding the truth in both hands with the blade. Azumi hovered close, her bare feet an inch off the timber. "You did it," she said. "The scary dog liked you." She grinned, wild and easy, the way she grinned at everything. Scarlett couldn't grin back. "Azumi. Land for a second." Azumi dropped. Her sneakers hit the wood. "What? Is it another trap? I can't read the dog, its brain's all fuzzy." Arachne folded her eight legs and settled by the far post. Her purple eyes moved from Scarlett to Azumi and back. She said nothing. She only waited, still as the rock she'd climbed from. Scarlett looked at the sword. Cthulhu's carved face stared up from the hilt, tentacles frozen mid-curl. The beast had read her heart and found one thing at the center of it. Not the boy. Her. "The beast bowed," Scarlett said. "You know why?" Azumi shrugged. "Because you're brave." "No." Scarlett set the blade down against the post. Her hands felt light without it. "Because of you. It felt what I feel when I look at you. That's what stopped it." Azumi went still. For once she didn't laugh. "What do you feel?" Scarlett's throat closed. She thought of turning it into a joke, the way they always did. Then she thought of the flood, the cold cave, every step she'd taken chasing the wrong person. "I love you," she said. "Not best-friend love. The real kind. I've loved you the whole way up this mountain and I was too scared to say it." The words hung in the cave air. The waterfall roared behind them, purple stones glowing along the runes. Azumi's green eyes filled. She stepped forward and pressed her forehead to Scarlett's. "I heard it," Azumi whispered. "Days ago. In your head. I waited for you to say it out loud." She laughed, wet and shaking. "You took forever." Scarlett laughed too. The fear drained out of her chest. She wrapped her arms around Azumi and held on. Arachne rose on her legs. "The beast bowed to a love unspoken," she said. "Now it is spoken. That changes what you carry." She nodded at the blade. "And who follows you." Scarlett pulled back. "Follows us?" Arachne pointed one dark leg past the open path. In the shadow beyond the bridge, something watched. Not the winged beast. Smaller. A pair of eyes low to the ground, tracking the sword's glow. The boy. He had come back. Scarlett picked up the blade. She had spoken her heart. Now the one she'd chased was watching her hold the thing he ran from.

The boy's eyes glowed in the dark past the bridge. Scarlett held the purple sword and felt the winged beast at her back. The creature had bowed to her love. But a bow was not loyalty. She needed a guardian strong enough to guard the party she still dreamed of throwing, the gathering that would steal the heart of Atlantis. The beast would follow her heart. It would not follow a stranger's orders. She had to earn it before it ever left this cave. Azumi drifted up beside her. "He came back for the sword," she whispered. "His head's screaming. He wants it and he's scared of it." The boy crept onto the timber. He reached for the blade in Scarlett's hands. "Give it to me," he said. "It's mine." Behind Scarlett, the winged creature rose. It was an aardwolf shape with dark bat wings and cold blue eyes. It watched the boy with the flat stare of a judge. Arachne climbed down the far post and settled on her eight legs. "It will not go with him," she said. "It knows what he carried and what he dropped." Scarlett understood. The beast tested hearts. It had already read the boy's and found only fear. She looked at the sword, then at the creature. "I'm not giving you this," she told the boy. "You ran from it. I carried it up the whole mountain." The boy lunged. Azumi shoved him back with both hands. He stumbled against the post. The winged beast stepped between them and bared its teeth. The boy froze, then backed toward the shadows and fled. Scarlett turned to the creature. It could still leave. It followed love, not commands. She knelt on the cold timber and laid the sword flat before it. "I'm not asking you to obey me," she said. "I want to build something. A place where people gather without being afraid. I need someone to keep them safe. Will you stay?" The beast lowered its head. It sniffed the blade, then her open hands. Its blue eyes searched her face. Scarlett held still and let it read everything, the love she'd spoken, the party she wanted, the fear she'd finally beaten. The creature pressed its warm muzzle into her palm. Arachne let out a low breath. "It has chosen you," she said. "Not the sword. You." Azumi laughed and threw her arms around Scarlett's neck. Nearby, a small campfire flickered to life among the runes, its flame throwing soft light and gentle warmth across the ledge. The winged beast folded its wings and settled beside the fire, close to Scarlett's knee. Scarlett rested her hand on its striped back. She had a guardian now. She had Azumi. She had the sword. What she didn't have was a way home, or any idea what the boy would tell the others waiting below.
