Reading Recs?

Since reading Andy Hoffman's book, I've had an insatiable craving for more just-for-fun reading. As long as the book has nothing to do with climate change or renewable energy (which I get more than enough of at school), I'll consider it. The problem is, it's been so long since I've had time to read for fun that I don't know where to start. What are your recommendations for really good, fun-to-read books?
