Talk Books to Me, Bebbeh

I'm planning on buying a bunch of audiobooks to listen to on my iPod while I exercise. Also, I've decided to really try not to use my car and walk to where I need to go, recommended by the new svelte and slim Stephen Fry who used this method to lose a ton of weight. Anyway, I think it's a great idea and I'm going to start, but I want some book recommendations. :D

So guys, what books do you guys think I should read/listen to? List them in the comments and then I'll compile them in a master list. Thanks!! :D
