Query: Half a great read!

When Klavan is writing from the point-of-view of newspaper man, Steve Everett, this book rocks...it would have ranked a ten if Everett's was the book's only POV. It's when the other voices kick in -- Frank Beachum, his wife, the warden, etc. -- that the novel crashes and burns, as if Everett himself were driving his beloved Tempo into a brick wall. A big disappointment.
