Things that make me go 'hmmm'

I was just looking at my dad's Amazon wish list for some Christmas gift ideas, and his three most recent additions are Looking for Alaska, Paper Towns, and An Abundance of Katherines. This is not his usual type of reading, so I'm really dying to ask him how and why he found out about these books and decided he wants them. Even though I'm always pestering my dad to use the library more instead of buying all his books, I think I know some books he'll be getting this year. Too bad I don't have a chance to get them autographed.
