I would recommend this book to anyone that wants to read about action. This book doesn\u2019t have anything-graphic content so it is suitable for all ages. The target audience for this book would probably been fourteen to fifteen year-olds solely due to the fact that Alex himself is fifteen. The story has a decent plot with one good twist but nothing very special. This book is basically a straightforward action book. So, if anyone wants a book with an abundance of action scenes, or has read the previous books in the series, this is the book for you.
