I really enjoyed that series. Probably my favorite series, though, at least in audio books, is the Aubrey-Maturin series by Patrick O'Brian, narrated by Simon Vance. The series has been recorded twice, and I've listened a bit to the other narrator, but didn't like him nearly as well. Vance seems to capture the nature of the individual characters amazingly well, and they are very well-drawn characters. I've run through the entire twenty-book series twice in order, and now I'm reading them randomly. There is a 21st book, but it's incomplete because the author died, and I haven't found the heart to take it on.
