Forgot, The Things They Carried is another great book. All about the relationship of Story Truth vs Objective Truth that weaves throughout all of the anecdotes being told. I think about it allllll the time.
Another one of my favorites is And Then There Were None by Agatha Christie. It's a murder mystery novel that plays off the 10 Little Indians nursery rhyme. Has some great characters and sort of has a classic feel to it, since it was written several decades ago.
