Query: Best yet!

This is a fantastic read that really delves into souls of the main characters more than ever before. It is a wild ride that pulls your heart along through the story. I found myself trying to coach Harry the teenager as I read, and I shed tears for him during his struggles. I only wish I hadn't read it so quickly--now I have to wait even longer for the next one!
