Every Door in This House Opens Inward

Hana Sato is fine. Everyone says so. Her desk is where she left it. Her key card works. Her boss is kind. But the floor plan keeps changing. A corridor that wasn't there on Monday. A stairwell one floor shorter than it should be. A door that opens inward, toward her, every time she checks. When Hana photographs the drafts at night, the changes are gone by morning. When she tells her colleagues, they look at her the way her psychiatrist does. Gently. She is not having an episode. She is having a witness problem. Because someone in this building is drawing a room that isn't on any plan — and the only way to prove it is to be the one woman nobody believes. A razor-sharp thriller about gaslighting, architecture, and the terrifying difference between being paranoid and being right.
