The Hobbit by J.R.R. Tolkien
A couple of my friends had wanted to read this at the same time as a sort of pseudo-book club, so I decided to join them. It was interesting to see a few little references to the events of The Silmarillion, like the mention of the sundering of the elves. Anyway, it's a fun book, but you probably already knew that considering what a well known classic it is.
