When Marek, Paul, and Lena follow a rumour to an abandoned orangery, they find a door that should not exist and a hidden city waiting just beyond the glass.
Marek stopped in front of the orangery and stared at the cracked glass doors. Sunlight slid across the broken panes, turning the whole place into a shimmer of warped reflections. Wind dragged through the dead leaves inside, carrying the smell of wet stone, dust, and something older than the building itself.
Paul let out a low whistle. Lena was already clutching the edge of her sleeve, her eyes fixed on the pale glow leaking from under the door.
None of them had meant to come this far. It had started with a message in the school chat room: Whoever finds the City Behind the Glass will get their greatest wish. At first, Marek had laughed it off. Rumours like that had a way of surviving every year at school, changing shape every time older students repeated them. But by lunch the joke had stopped feeling harmless, and by the time the three of them reached the edge of the city, Marek had the uneasy sense that something had already begun without them.
Lena bent down near the threshold and picked up a folded scrap of paper from the dead grass. She opened it carefully, as if it might tear in her hands.
"Marek," she whispered, "look at this."
The note was covered in cramped writing, the ink smudged by rain: Enter where the light casts its shadow. Stand on the threshold and close your eyes. What you fear will show you the way.
Paul gave a nervous laugh that sounded too loud in the silence. Then thunder rolled over the rooftops, and lightning flashed across the orangery windows. For one sharp second, the glass looked less like a wall and more like a surface stretched thin over something moving underneath it.
Paul stepped closer. Before Marek could stop him, he pressed his palm to the door.
His hand vanished.
Lena gasped. Marek grabbed Paul by the arm and yanked him back just as he jerked away from the glass, pale and shaken.
"That is not normal glass," Paul muttered.
No one answered. The air had changed. It felt charged, almost breathing, and beyond the door the light bent in strange angles, as if the space on the other side did not quite belong to the same world.
Marek looked at his friends, then at the threshold, and knew they had reached the point where turning back would feel worse than going on.
He closed his eyes and stepped forward.
For a heartbeat there was only cold, a pressure against his skin, and the sound of Lena following close behind. Then the air split open around them, and Marek opened his eyes to a city that had not been there before: towers of glass and silver rising into the mist, bridges hanging between them like threads, streets lit by colours that shifted when he looked straight at them. Figures moved in the distance, too tall and too still to be ordinary people.
Somewhere nearby, a laugh rang out, soft and sharp at once.
In the square ahead, a map began to glow in midair, lines drawing themselves one by one as if an unseen hand were marking their place.
Then the shadows at the edge of the street shifted, and a figure with translucent eyes stepped into view and held out a hand toward them.
