Audio/Podiobook suggestions?

I'm searching for a way to improve my pronunciation and listening skills in English. Since most of my movie squees are Korean or Japanese these days, I thought about audio (or podio) books, but am a bit of a loss as to where to find some with an interesting story (to keep me listening) and good speakers.
I'm currently listening to the podiobook of "The Emperor's Edge" by Lindsay Buroker, but I'd like to vary speakers not to get myself a dialect or a singly tuned hearing, so to speak.

Do you know of other good audiobooks (freebies or not)?
I'd love to get your suggestions.

In any case: please receive the season greetings of your preference. :-)
