Ola and Antek find a hidden door in an old school and step into a world that should not exist. What waits beyond it is stranger, and far closer, than they expected.
The school felt wrong that afternoon. Rain rattled the windows, the hallway lights buzzed overhead, and every sound seemed to flatten into the damp, uneasy air. Ola kept her head down as she followed Antek along the third-floor corridor, her rucksack slipping against her shoulder.
“Say it again,” she murmured. “How did you find this door?”
Antek slowed just enough to look back. “Yesterday, after lessons. I was helping Grześ with chemistry and got turned around. At the end of the corridor, there it was. No label. No classroom number. Just 22, written in chalk.” His mouth tightened. “And the handle was hot.”
Ola stopped walking. “Hot?”
“I know.”
The corridor ahead was empty now, the kind of empty that made the school seem abandoned rather than merely quiet. At the far end, beneath a water-stained ceiling, stood a door that did not belong with the rest. Its paint had blistered with age, the frame was webbed with dust, and the number 22 glimmered faintly in white chalk as if someone had written it moments ago.
Ola stared at it longer than she meant to. Something in her chest kept pulling back, but she could not tell whether it was fear or curiosity. She reached out, then drew her hand away before touching the handle.
“Maybe it’s just a storage room,” she said, though neither of them sounded convinced.
“A storage room doesn’t glow,” Antek replied.
That made her look at him.
He took the last step first. His fingers closed around the handle.
The metal was not merely warm. It pulsed, as if a heartbeat lived inside it.
Before Ola could warn him, the air shivered. A thin line of blue light split the edge of the door, bright enough to make both of them flinch. The corridor lights flickered. Somewhere behind them, a locker slammed shut.
Antek pulled the door open.
There was no boiler room, no stack of broken desks, no smell of dust and bleach. Beyond the threshold spread a vast, silent expanse of mirrored tiles that caught the light and sent it skimming away in silver and gold. Above it hung a sky filled with stars, sharp and close as scattered glass, impossible beneath the school roof.
Ola forgot to breathe.
They stepped through anyway.
The door closed behind them with a sound like a distant bell, and the world shifted under their feet. The mirror-floor stretched farther than sight, broken here and there by moving shapes of light that looked almost human until they vanished. The air hummed around them, thin and electric, as if the whole place were listening.
Ola looked down at her reflection and felt her stomach drop.
The face staring back at her was hers, but older. Harder. The eyes were the same shape, but the expression belonged to someone who had seen something she had not.
“Antek...” Her voice came back to her from every direction at once. “Where are we?”
He did not answer.
He was staring past her shoulder.
A sound had started somewhere in the distance, slow and regular, like footsteps crossing the glass toward them. One. Then another. Then a third.
And in the mirrored floor at Ola’s feet, a second pair of footsteps appeared behind hers.
