A haunting psychological horror novel by Marcus Kliewer, published in 2024. Expanding on the author's viral internet horror story, the novel blends psychological suspense, uncanny horror, and mystery into one of the year's most talked-about debuts.

Young couple Eve and Charlie have recently purchased an old, isolated house to renovate and turn into their dream home. One evening, a stranger named Thomas Faust arrives at their door with his family, claiming they once lived in the house and asking if they can briefly look around for sentimental reasons.

What begins as an awkward but harmless visit quickly becomes deeply unsettling. The visitors behave as though they still belong there, know details they shouldn't, and seem strangely unwilling—or unable—to leave. As the hours pass, reality itself begins to feel unstable. Rooms appear different, memories become unreliable, people seem to change, and Eve can no longer trust her own perceptions.

As the mystery deepens, the novel transforms into a chilling exploration of identity, memory, liminal spaces, and the terrifying possibility that home itself may not be what it seems. Kliewer deliberately blurs the line between psychological breakdown and supernatural horror, keeping readers questioning what is real until the final pages.

Atmospheric, unsettling, and relentlessly suspenseful, We Used to Live Here is a modern horror novel that relies on mounting dread and uncanny ambiguity rather than graphic violence.
