Mary holds the book in both hands and watches its cover fall open without her touching it. The pages are blank. All of them. She knows what they need from her — the same thing everything needs from a mirror. Not words or wishes, but proof that she exists. She presses her thumb against the book's edge until skin splits. One drop falls. Then another. The pages drink them in, and where her blood touches, lines begin to form. The lines stretch and curve, becoming a figure. A woman in white, face pale, red hair vivid against the drawn veil. Blood marks stain the drawn fabric. The image is crude but precise, like something carved rather than painted. Mary recognizes what she's looking at. A portrait of herself. Not as she sees herself, but as the book sees her. As something already claimed. She turns the page. The next one shows a pentagram drawn in black against white. Five points, perfect and stark. She's seen this before. Outside, in the snow behind the castle, where she stood three days ago and felt the cold through her boots. The book is showing her where she's been. What she's marked without meaning to. The charcoal lines in the snow weren't random. They were hers. Mary closes the book and feels its weight settle differently in her hands. Heavier now. The blank pages are gone. The book has her blood, her face, her footsteps. It knows what she is and what she wants. To show people what they hide from themselves, she needs to see what they truly are. The book will help her do that. It already has her reflection. Now it needs theirs.

Mary carries the book back through the mansion's corridors, feeling its weight shift with each step. It knows her now. Her blood, her face, her marks in the snow. But knowing her isn't enough. The book showed her what it could do with one reflection. Now she needs to see what happens when it gets another. Void is in the east wing, standing where the floorboards creak. Mary doesn't call out to him. She simply opens the book and holds it steady. The pages bleed again, but this time the blood isn't hers. Black ink spreads across the white like shadows pooling under moonlight. The portrait that forms is nothing like the one the book made of her. This one shows horns curving from a hooded figure, wings spread wide, eyes pale and hollow. The drawing is beautiful in the way sharp things are beautiful — precise enough to cut. Beneath the figure, tendrils twist and spiral across the page, spreading like roots seeking water. They move even after the ink settles, curling outward in patterns that make Mary's eyes ache if she looks too long. She tilts the book toward Void. He doesn't flinch. He looks at the portrait the way someone might look at their own name carved into stone. Recognition without surprise. The tendrils stop moving. The page goes still. Mary closes the book and feels the difference immediately. It's heavier now. Not from weight, but from what it holds. Two reflections instead of one. She wanted to see if the book could show what someone hides from themselves. It did more than that. It showed her what Void already knows he is — the truth he doesn't bother hiding because he's never tried to look away from it. That wasn't the test she meant to run, but it taught her something sharper. The book doesn't wound people by revealing secrets. It wounds them by drawing what they refuse to see. Void has nothing to refuse. Which means the next reflection she feeds it needs to come from someone who does.

The book grows heavier in Mary's arms as she walks. By the time she reaches the east wing's far door, it shudders against her ribs. Void follows a step behind. Neither of them speaks. The pages are pulling at something, and Mary can feel the pull in her own chest, like a hook set behind the bone. They end up in a stone chamber she has not seen before. An archway stands at its center, swirling with dark light, fragments of mirror set into its frame. Each shard shows a different sliver of them — her hand, his wing, her eye, his mouth. The book wants to be opened here. Mary knows it the way she knows her own reflection. She sets the book on a flat dark tablet near the arch. The tablet's surface catches starlight that isn't there. The pages flip themselves. Her portrait surfaces on the left. Void's surfaces on the right. Between them, lines begin to draw — thin black threads reaching from her image to his, from his to hers, knotting in the middle of the spine. Mary feels it then. Something she has not named, even to herself, lifts in her throat and tries to climb onto the page. She sees Void's jaw tighten. Whatever he refuses to want is being dragged up beside her secret. Across the chamber, a pale statue of two shadowed figures locked in an embrace begins to crack along its seams. The strain is not in the stone. The strain is in them. "Close it," Void says. His voice is quieter than usual. "Mary. Close it now." She slams the book shut. The threads snap. The statue settles with a long, low sound, fracture lines stopped halfway through. Mary lifts the book from the tablet and feels how it has changed — lighter by exactly what it almost took. She did not master it. She stopped it. That is not the same thing. Void does not look at her, and she does not look at him, and the space between them now has a shape it did not have before.

Mary carried the book back to her room and set it on the desk. She did not open it. Even shut, it pulled at her chest, thinner now but still there, like a thread tied behind the ribs. She slept badly. In the morning, the pull had changed direction. It no longer tugged toward the book. It tugged toward the chamber they had left. She found Void in the east wing hall. He was standing very still, one hand at his side. "You feel it too," she said. He nodded once. "Since last night. It's coming from the statue." His voice was lower than usual. "Something is leaking out of the crack." They went back down together. The stone chamber smelled wrong now — wet iron, and under it something sweeter. The statue of the two embracing figures stood where they had left it, half-fractured. A pale grey vapor slid from the seam between the two shadowed bodies. It did not rise. It moved along the floor toward Mary's feet. When she stepped back, it stopped. When she stepped forward, it reached. "It wants what the book started," Void said. "The part you closed off before it could finish." Mary understood then. The book had pulled something up out of them and had not put it back. The statue had cracked holding what spilled. Now the crack was open and the thing inside was hunting the person it half-knew. Her. She set the book on the tablet again. She did not open it. "If I open the book here, it will feed. If I leave, it follows me out." Void was quiet for a long time. "Then we don't feed it and we don't let it follow. We seal it." He drew his blade and cut his palm. He pressed the cut against the fracture in the stone. "Put your hand next to mine. Don't open the book. Just hold it against the seam." Mary did. The vapor stilled against the cover. The book grew warm, then cold. She felt the pull in her chest thin further, then snap clean. The fracture in the statue closed under Void's blood, sealing to a thin dark line. The vapor drew back inside and did not return. She lifted the book. It was lighter again. Two closings now. Two things it had almost shown and had not. Void wrapped his hand in the edge of his cloak. He looked at her for the first time in a day. "I don't know what we sealed in there," he said. "I know it was ours." Mary nodded. She had wanted to master the book by using it. Twice now she had mastered it by refusing it. That was not the same skill. She would need the other. And she would need a face that could not close, next time — someone who could not press their palm to a crack and stop the truth from coming out.

The sealing had held for a day. Mary knew this because she had watched the statue's dark seam every hour and found it still closed. What had not held was inside her. When she passed a window that morning, her reflection lagged. Only a beat. But her reflection was her craft, and a beat was a crack. She went to her room and sat at the black dresser. The oval mirror above it had shown her face without trouble her whole existence. Now it showed her red hair, her white dress, her stare — and behind her left shoulder, a smear of pale grey that was not in the room. She turned. The room was empty. She turned back. The smear was still there, riding her like a second coat. A coat that doesn't fit, called skin. She had said those words about other people. She had not planned to wear them. She understood what had happened. When she and Void sealed the crack, the vapor had drawn back — but not all of it. A trace had stayed in her, in the part that looks. If it grew, she would read every face through it. She would see her own smear on strangers and call it their truth. Her work would become a lie. She needed a mirror that could not lie back. She left the mansion and walked to the reflective structure at the edge of the grounds, the one stained with red streaks that never washed off. Inside its entrance hall she took from her satchel the small framed glass Void had given her weeks ago — the one with the burned red-and-black mark seared into its center. A mirror that already held a corrupted image could not be tricked by another. She set the small mirror against the wall so its burn faced her. Then she stood between it and the tall reflective panel opposite. Two mirrors, one behind, one ahead. She made herself look forward. Her reflection in the tall panel carried the grey smear. She turned her eyes to the small mirror. Its burn held steady — no smear crossed it, because the glass was already claimed. The trace in her had nothing to grip. She watched the smear in the front panel thin. She kept her eyes on the burn and did not blink. On a branch outside the doorway, a white owl with amber eyes watched her without moving. She used its stare to steady her own. When she looked back at the tall panel, the smear was gone. Her reflection matched her body again, beat for beat. She wrapped the small mirror and put it away. Her sight was hers again. But she had learned something she did not want to know: the book had not only pulled things out of her in the chamber. It had left something in. Whatever else it had planted, she would not find by refusing to look. She would have to open it on someone who could not close.
