At a strange high school, Lena notices the old building bending light in impossible ways. With Igor and Tim, she follows a trail of missing shadows toward a door that should not exist.
School No. 17 had always felt wrong in ways Lena could not explain. The new wing was ordinary enough, all bright paint and locked lockers, but the old part of the building seemed to hold its breath. Its staircase was cracked down the middle, the walls stained a tired grey-green, and the great clock above the entrance sometimes seemed to lag behind the rest of the world by a second or two.
Lena had noticed more than that. Once, she had seen the shadow beneath the clock stop moving while everything else in the corridor kept going. She had told no one, not even Igor and Tim, because the idea sounded ridiculous the moment it was spoken aloud.
Today, she decided she was done pretending the school was ordinary.
"Listen," she said during the break, lowering herself onto the old bench by the maths room. Her voice came out quieter than she expected, as if the walls themselves were listening. "There’s something in this school. Something we keep missing because we’re not looking properly."
Igor gave her a sceptical smile, but Tim leaned in at once.
"Something like what?"
Lena pulled a small hardcover notebook from her backpack. The corners were bent, the pages crowded with rushed sketches and cramped notes: a door that wasn’t there the first time, a shadow that failed to return, a sound like breathing in an empty hall.
"I’ve been keeping track," she said. "And I need you both to help me check one last thing."
The old floor was nearly empty after lessons. The fluorescent lights flickered overhead, turning the corridor into a sequence of pale flashes and deeper dark. By the time they reached the wall Lena had marked in her notebook, the air had gone cold enough to raise goosebumps along her arms.
She pressed her hand against the rough plaster and brushed away a smear of dust.
Her breath caught.
On the wall, there should have been three shadows. Instead, there was only light.
Lena stared at her hand, then at the empty grey surface beside it. Igor swore under his breath. Tim lifted his hand slowly, as if expecting the world to correct itself if he moved carefully enough. But his shadow was gone too.
"That’s not possible," he whispered.
The wall answered with a low, shivering pulse. A hairline crack split through the plaster, then another, and another, each one tracing a shape that had not been there a second before. Lena stepped back, her pulse hammering.
From behind the wall came a faint whisper, soft as paper dragged across stone.
It sounded like someone saying their names.
