Okay, I got so many responses that I decided to cut nominations short. So here's the process: I'm going to keep this list as a master list, and I need you guys to vote for your pick. I think I'll tentatively say that the cutoff will be Wednesday. Also, where someone suggested a later book in a series I decided to go with the first one instead.
Thank you to DEMOLITIONBEANSÍDHE for the poll!
