I am highly impressed with Jonathan Renshaw's debut novel. The pacing feels good, plot is interesting, and the characters are great. 
 Better yet, I can recommend it without reservation. There is not only no sexual innuendo, but no bad language either. In that light it's good for all ages. That said, while the characters are young teens, I wouldn't consider this a children's story. It is mature in style, and presents some thought provoking material. 
 To cap off a great story, it is read by the fabulous Tim Gerard Reynolds. I believe this series will be a worthy addition to his resume. 
 I'm looking forward to the next book.
