This book was quite al right, exactly what you would expect from this kind of book, and in that maybe slightly predictable. The characters weren't as worked out as they could be, but it has enough potential for growth in later books, as this is part of a series. The fifteen year old protagonist acts a little bit below his age, I would expect a little bit more responsibility from him, especially concerning his younger brother, that gets into trouble quite a lot. The book mostly consists of a lot of action scenes, and that is the strenght of it. Other than those there wasn't that much of a strong story line going on. This book will probably appeal to younger boys quite a lot, there is enough adventure to keep 'em happy for a few hours. This book isn't suitable for a too young audience though, some scenes are quite gruesome.
