Wizard's First Rule

I just finished reading Wizard's First Rule by Terry Goodkind. I've been reading the Sword of Truth series all out of order. I started on book 9 of the series Chainfire because I saw it at the book store in an MP3 format. I really prefer the audio books in MP3 format already and that one was on 2 discs. This book was also in MP3 format already but in comparison to the number of discs, I listened Phantom (book 10) and it was on 20 discs.
