What are YOU reading?

Since some people responding to a previous post that they did, in fact, also read multiple books at a time, I began to wonder what those books were. When you have multiple books going at once, are they all similar? Or are they different types of reading?

I usually have different kinds of books going at once. For example, currently, I am reading Revolutionary Road, Pen on Fire, Making It All Work, Creating True Peace, and The Well-Educated Mind. So that's a novel, a book about writing, a self-help type productivity book, a spiritual book, and a book about--well, other books! I read Pen on Fire before bed because Rev. Road is a little depressing. So I read that during the day. Making It All Work is on my iPod for the gym, and the other two I've been dabbling in when I want a break from the others. Sometimes, if I am reading two novels, I'll have one light one and another that's a bit more substantial.

So, what are you all reading right now? Anything good?
