Invisible Monsters of all his I have read.....my mouth was hanging open in shock the last few chapters! Please don't skip ahead and spoil it for yourself.
I haven't read Fight Club (seen the film obviously)...is that his "masterpiece" do you think?
I liked Invisible Monsters the best but Haunted is a close second. I didn't really like Fight Club as much has I had imagined I would, probably because I had seen the movie before reading the book.
