On a rainy afternoon, Lena notices a shelf in the school library that does not belong where it is. Behind it waits a hidden passage, a cold breath of air, and something with silver wings.
Lena always liked the school library best when it rained. The windows blurred with water, the hallway outside went quiet, and even Mrs Zosia’s keyboard seemed to tap more softly. Between the bookcases, the air smelled of dust, paper, and the faint sweetness of old glue.
Lena drifted from shelf to shelf, running her fingertips along the book spines. Most of the titles were familiar, but at the far end of the darkest row she stopped. The shelf there looked a little crooked, as if it had been nudged out of place and never set back properly. Its books were stranger than the others: Atlas of Star Gardens, How to Talk to Trees, Guide to the Invisible. Lena frowned and crouched down.
Something gleamed near the bottom edge. A brass handle. Tiny, dull with age, and shaped like it belonged on a cupboard door, not a bookcase. Lena glanced over her shoulder. Mrs Zosia was nowhere in sight. Her pulse quickened. She wrapped her fingers around the handle and pulled.
The shelf gave a long, complaining creak. Then, very slowly, it swung away from the wall.
Behind it was a narrow gap no wider than her shoulders. Cool air brushed Lena’s face, carrying the smell of wet moss and something older, deeper, like pages that had been hidden for years. Far inside the dark passage, a blue light flickered once and vanished.
Lena stared.
She was just about to step forward when something rustled beside her, light as turning paper. A shadow slid out of the darkness, low to the ground at first, then lifting its head. It looked like a cat.
Almost.
Silver wings unfolded in the dimness.
