Leon and Zosia find a hidden portal in the school library and step into a world of black glass, shifting reflections, and a trial that may be the only way back.
Leon had always suspected that his school was holding its breath. Behind the polished corridors, the locked storerooms, and the oldest wing of the building, something felt unfinished, as if the place had been built around a secret no one remembered anymore. The library was where that feeling was strongest. Among the towering shelves and dust-soft light, Leon always had the strange sense that he was standing one step outside ordinary time.
On Friday evening, long after the last bell, he and Zosia were still there, supposedly helping Mrs Jola sort books. In truth, neither of them had been able to resist the quiet pull of staying behind. Zosia was the one who found the volume first: Labyrinths of Time, its spine half-hidden between two heavy encyclopedias. She tugged it free, and the air changed at once. A cold draft moved through the room, sharp enough to raise the hairs on Leon’s arms.
He followed the breeze to the darkest corner of the library, where a metal sign marked Special Collections. At the base of the wall, just above the floor, there was a crack so narrow he could have missed it if he had blinked. It did not look old. It looked deliberate.
Leon crouched, hesitated only a second, then slid his fingers into the seam. The wall gave way with a low, mechanical sigh, swinging inward as if it had been waiting for him all along. Zosia appeared beside him so suddenly that he almost flinched.
Beyond the hidden door was a corridor cut from darkness. At the far end, a blue light pulsed faintly, like a heartbeat seen through water. Leon switched on his phone torch, but the beam seemed thin and uncertain in that blackness. Zosia caught his hand.
"Do we really go in?" she whispered.
Leon looked back once, at the library they knew, at the ordinary world still standing safely behind them. Then he faced the corridor again. Something inside him, something restless and long-suppressed, had already answered.
"We have to," he said.
The passage was longer than it should have been, bending in ways the school could not possibly allow. When they finally reached the light, the corridor opened into a vast hall with walls of black glass. In its centre floated a crystal-shaped core, threading the air with colours that shifted too fast to name. Every surface around them held a reflection, but none of them matched properly. Some showed Leon and Zosia older. Some younger. Some were almost them, and some were not human at all.
Then a voice came from somewhere behind the crystal, soft and close, as if speaking through a locked door.
"Welcome, explorers. The trial has begun. Will you find the exit before time runs out?"
Zosia went rigid beside him. Leon turned toward the sound, and in the same instant the glass beneath their feet gave a sharp, hairline crack.
