It took a little while to get going, but it was worth it. The mystery at the center of the book is certainly very well done, which makes the book deserving of the Edgar Award it won. Gib is also a pretty cool kid who knows what he needs to do and not how to do it. All in all, a really good concept. However, aside from Gib, the characters aren't terribly interesting, original, or memorable, and that's a royal shame because that could've made the book into an instant classic. Nevertheless, it's a pretty fun, quick read that may be worth revisiting and that kids will like a lot.
