The Lost Floors A Liminal Horror Novel: A Descent into Endless Rooms, Shifting Reality, and the Horrors Beneath

By Mahmoud Osman

The Lost Floors: A Liminal Horror Novel

No elevators. No exits. No end.

When nineteen-year-old Evan Carter steps into an ordinary supply closet at his new job, he expects to find cleaning supplies-not a stairwell leading into nowhere. Each descending floor becomes stranger, emptier, and more wrong than the last: buzzing yellow halls, abandoned hotel corridors, dripping concrete tunnels, and offices frozen in time.

Something lives down here.
Something that listens when you breathe.

Evan joins forces with Mara, a girl who claims she's been trapped for months-but the more they descend, the less Evan trusts her... or himself. The floors shift. The walls whisper. Memories rearrange themselves. And every time they think they've reached bottom-

The building grows another level.

To escape, they'll have to face the truth buried at the deepest floor... a truth the structure will kill to protect.

A slow-burn, psychological descent into liminal horror-perfect for fans of House of Leaves, The Backrooms, and Silent Hill.
