I'm closing off my audible account and I have 5 credits (books) to use before I cancel. I dig biographies and really good fiction. I've recently read (in book form) Slash, I Am Ozzy, Dirt, and the Mackenzie Phillips bio (what a facked up life!). Audio books I've gone through in the last couple of years are the ender's game series (main story), Artie Lange's bio, Paul Shaffer's bio, Shatner's bio, and a cool sci-fi series called Spin. I've got an interesting one to listen to still called Outliers. These are mostly to listen to on a treadmill or in the car.
Here are the 2 I'm sold on. If you've got some suggestions, please post a reply.
