The Last Door in the Building

When Mara Jennings insists there's a door at the end of her hallway, her neighbors laugh. Her landlord rolls his eyes. The building manager swears no such door exists. But Mara sees it. A tall, dark, wooden door that moves. Some days it's beside the stairwell. Other days it's opposite her apartment. And when she works up the courage to open it… she steps into a version of her building where something is always just slightly wrong. Rooms have changed shape. Neighbors don't know her. Photographs show memories she never lived. And in some timelines, she doesn't exist at all. Each time she returns, the door appears closer, more deliberate—like it's choosing her. And the more Mara tries to escape it, the more reality around her fractures: voices echoing from empty rooms, shifts in time, and reflections that lag behind. To survive the door's pull, Mara must uncover the truth about her place in the building—and confront the version of herself that lives on the other side. The Last Door in the Building is a tense, reality-bending psychological thriller perfect for fans of House of Leaves, Black Mirror, and eerie multiverse suspense stories.
