I'm curious if anyone out there might have some advice for me.  For my birthday, I was given a gift allowing me to download an audio book from a website called Audible.  I'm super-excited to give this a try -- but to be honest, I don't have any real experience with audio books.

So I'm wondering:  Are there any special considerations for choosing an audio book?  Are there any particular authors out there who are especially enjoyable by audio?  In short:  Do you have any recommendations for how I should go about my first real audio book experience?

I'd appreciate any and all input that you might have for me.
