What do you read for fun?

When it comes to reading for fun, what do you read? I tend to read more than one book at a time. I'm currently reading Cats Cradle (I am loving this book so far), and Grapes of Wrath (It's been a goal of mine to read this one for a while, I love the use of language and I feel like I'm in the Dust Bowl). I was reading Atlas Shrugged but halfway through I got distracted. I enjoyed The Fountainhead a bit more. When I have more downtime I cannot wait to be able to return to my first love, reading.
