If you're still trying to think of books for the Halloween Bingo game, House of Leaves would be an excellent choice for a number of squares.
I read it a while back, but for some reason I hadn't added it my Booklikes shelves. I stumbled across my paperback copy this morning. (To be honest, I'm not sure how I'd missed it earlier seeing as it's bloody enormous).
Haunted houses, things that go bump in the night, unreliable narrators... what more do you need?
