I feel bad about giving this as low a rating as I did, but I'd received this via the Simon & Schuster Galley Grabs & needed to post a review for it. I didn't get into it enough to finish it but I don't feel that it deserves a low rating. 
 I just want to say that while I wasn't immediately sucked into this book, I can easily see where it will be extremely EXTREMELY appealing to its target audience. Mull has a nice writing style to him & the characters are interesting enough. I know for a fact that my nephew will probably be bugging me to buy him a copy for his birthday or Christmas- he's liked the other stuff that Mull has written. 
 If you've liked his other stuff then rest assured that this will more than likely be everything you hope it'll be.
