So I'm thinking of downloading some audio books that I can listen to at the gym while I'm walking on the treadmill (since it's so boring!). Does anyone have any good recommendations? I haven't read any of Janet Evanovich's books, and I keep hearing good things about her books. Also, does anyone know of a good (cheap) site I can get the audio books? I'm looking at Borders right now, but I should probably look around to see if I can get these cheaper anywhere else.

Thanks in advance for your suggestions!

Audible is very reasonable, if you signup for one of their plans. As for books, really anything that you find interesting will work. I personally love Harry Potter, C.S. Lewis' Space Trilogy, The Hitchhiker's Guide to the Galaxy Trilogy, LOTR, Dracula, etc.
