I really enjoyed the books in the Lightbringer series. Unfortunately, the first book (The Black Prism) is terribly done in audio.
If I may be so non-humble, I write reviews for SFFAudio.com, so if you're looking for science fiction and fantasy books, check there for sure.
I'm pretty to see that Tad Williams' Otherland books are now in audio. The narrator seems good so far, but I'm only about an hour in.
