Das Haus by Mark Z. Danielewski

A fragmented, multi-voiced horror novel that follows a family who discover their new house contains impossible, ever-shifting interior spaces—corridors and rooms that grow and change, forming a dark, maze-like void—and a scholarly, obsessive manuscript analyzing a documentary about those alterations interleaves with a second narrator’s collapsing sanity; through footnotes, marginalia and typographic experimentation the book becomes a layered meditation on fear, love, obsession and the unstable boundaries between story and reality.
