@dreams: Well, if you're looking for something to listen to in the car, can I suggest the Aubrey/Maturin series by Patrick O'Brian? The unabridged readings by Patrick Tull are exceptional and the Simon Vance versions are quite acceptable, though I don't think they're quite up to Mr. Tull's versions. (But listen to the samples to decide which you prefer, certainly.) Even if you've read this series as conventional books, they make excellent Audible books as well. And you have 21 books in the series, so it will keep you occupied for quite a while.
