Seventeen-year-old Lena takes a forbidden shortcut through the old high school and stumbles into a hidden corridor of mirrors, where the rules of the school stop making sense and someone she thought was gone is waiting inside.
Lena had always belonged to the hours other people slept through. By the time the boarding house settled into silence and the city beyond the windows dulled to a blur of sodium light and rain, she felt sharp enough to cut through the dark. That night, crossing the courtyard behind the old high school, she could smell wet stone and rusted iron, and the lanterns strung above the path shivered in the wind like nervous eyes.
She should have taken the main entrance. Instead, she cut toward the south wing, the part of the building everyone at school talked about in low voices and then pretended not to remember. The stories changed depending on who told them. Some swore there was a sealed stairwell behind the peeling plaster. Some said the walls carried echoes. Some said a passage opened only when the moon hit the windows at the right angle.
Lena found the door by accident, or maybe the door found her. It was half-hidden beneath a veil of ivy and tarnished green with age, its handle cold enough to sting. She hesitated only a second before pushing it open. The door gave with a sound like a tired sigh, and the air inside closed around her: cooler, damp, charged with something that felt uncomfortably close to a storm about to break.
Her phone torch was useless. The light thinned the shadows instead of pushing them back, as if the dark knew how to drink it. She stepped into a narrow corridor lined with cracked mirrors set between the walls, each one clouded with age. At first she saw only her own face reflected back at her: pale, tense, watchful. Then the reflection smiled.
Lena stopped so fast her breath caught in her throat.
The smile in the glass did not belong to her. It was too certain, too calm. Behind her, somewhere deeper in the corridor, a soft laugh broke apart into whispers. Her pulse kicked hard. She turned, but the hall behind her had already shifted; the door she had entered through was gone, replaced by more mirror, more hallway, more impossible angles folding into themselves.
Then the mirrors began to move.
A hand appeared in one pane, pressing from the other side as if testing the surface. The reflection lifted its fingers in a slow, deliberate gesture, urging her forward. Lena felt the air tighten around her, a pressure in her ears, a strange pull under her skin. Her phone flickered once, twice, and then the light flashed white so suddenly she nearly dropped it.
Halfway down the corridor, she saw someone standing very still.
Michael.
He was in her class, or had been. He had vanished from the boarding school three weeks ago, leaving behind an empty desk, unanswered questions, and rumours nobody could prove. Now he stood in front of a mirror with his face half in shadow, staring at her as if he had been waiting. His reflection was wrong too, lagging a fraction behind him, like it belonged to someone else entirely.
Lena took one step toward him. The floor shifted beneath her, a subtle tilt that sent cold panic up her spine.
A third figure emerged from the mirror behind Michael, and the glass rippled around her like water disturbed from below. She was older, dressed in dark clothes that seemed to hold the light rather than reflect it, and silver sparks burned in her eyes when she looked at Lena.
Her voice came from everywhere at once.
“Only one of you can return. Which will choose the key, and which will choose the mirror?”
