I was just about to post this when I saw your comment. Yeah, when we accidentally got the non-Marster's (still good) audiobook my wife and I were immediately like "this is not right". Master's is the only audiobook personality I know and is talked about by fans all the time (think he used to be in Buffy).

For anyone who hasn't ever read the Dresden Files, it is a fantasy series set in modern Chicago with a young wizard way in over his head. The series starts off kinda bleh with the first few books, but steadily picks up pace as the main character gets more involved with all the crazy things going on. The author puts basically every single (ok a lot) of diverse mythologies as if it is all real (Odin, Mab, Erlking, Skinwalkers, Trolls, the Fae, Necromancers, 4 different kinds of Vampires, Roman Gods, the White God, Angels, Demons, Lucifer, Dragons, Cthulhu, and about a dozen other bad and good things all with a single coherant plot. The main character starts to see that all of these major supernatural entities are moving their armies like 3D chess. The characters take some time to develop, but are seriously good.
