House of Leaves, it's an experimental horror novel that was famous for having crazy typesetting (and it's also very good, independently). It's about a house that's bigger on the inside than the outside and how that drives people insane.
I'm not sure it drove Navidson insane, but maybe it presented him a sane choice (staying safe with his wife) and an insane choice (risking everything to find out what is inside). And a certain type of person just can't let it be, even at the cost of everything. Maybe this was inside him all the time, and then the house happened.
