Seventeen-year-old Lena and her friend Filip uncover a hidden portal in an abandoned library server room and step into a world where time runs backwards and strange masked figures are already waiting.
The library windows caught the June light and threw it back in shards of gold. Lena had spent the whole afternoon drifting through the abandoned rooms off Matemblewska Street, following instinct, old floor plans, and the kind of curiosity that never let her walk away once she smelled a secret. The building was due to close for good, but to her and Filip it still felt alive, full of locked doors, forgotten wings, and dust-covered corridors that seemed to rearrange themselves when no one was looking.
They had found the basement by accident, or maybe the basement had found them. Behind a sagging shelf of drama books, an overburnt key fit a narrow rusted lock no one should have bothered to make. The door opened on a breath of cold air and a weak blue pulse from inside the room. Old servers stood in rows like sleeping machines, but it was the object in the centre that stopped Lena cold: a glass sphere bound in metal rings, each ring etched like a constellation, each one turning slowly though nothing else in the room moved.
Lena stepped closer before Filip could stop her. The sphere hummed under her fingertips. The nearest ring shivered, and for one bright second the air looked liquid, as if the room had been submerged under invisible heat. Then the light burst white.
When it faded, they were standing in the middle of a stone square under a sky too high to trust. Around them rose towers of coloured glass, spiralling upward in impossible curves. Birds made of light crossed the air in silent flocks. The ground beneath Lena's shoes felt warm, almost breathing.
Filip stared at the city, then at her. "Tell me you know where we are."
Lena opened her mouth, but the words would not come. A group of masked figures had appeared at the edge of the square, their faces painted with the symbols of the zodiac. They watched without moving, speaking in a low language Lena could not understand. One of them, tall and gold-masked like a lion, reached out and touched her shoulder with gloved fingers, as if checking she was real.
Another figure, wrapped in blue spirals, lifted a hand and pointed toward a gate glowing at the far end of the square. Above it hung a clock face with no numbers, its hands turning the wrong way. Lena felt every nerve in her body tighten. Somewhere in the glass towers, something was watching them back.
Filip squeezed her hand hard. "We go," he said, though it sounded less like a choice than a warning.
They started toward the gate. The clock above it snapped still. The square lurched around them, bending and shifting like a reflected image in broken glass, and a trail of light flashed overhead, leading straight into the darkness beyond the threshold.
