My mom gave me the book to listen too, and said I would enjoy it. I was a little hesitant because it seemed to be like a little kid book..... but I really did like it. I thought some of the characters and things in the book were extremely creative! It was a book appropriate for kids and young teenagers, but still had a good amount of substance. I liked the characters and think they have promise, I might even get the next book instead of waiting for my mom to lend it to me so I can see how well the author builds up the characters.
