I just finished The Art of the Infinite: The Pleasures of Mathematics by Robert and Ellen Kaplan. It's a very entertaining book if you are into mathematics. The comments and asides make for a very clever writing style and not what you might expect. The two professors are very good writers aside from the math, and you don't have to be a mathematician to appreciate the book.
But then, my wife says I'm a nerd for reading such things, so there is my disclaimer.
I also recently read The Last Passenger by Manel Loureiro. It's OK for putting yourself to sleep at night, but it's really pretty weak over all. I do not recommend it. But since I got it cheap on the Kindle, I'm good.
