This is an almost non-stop action thrill ride. Once it gets going there's barely any down time which isn't really a bad thing. There isn't that much character development, while the characters are done well there isn't much relationship growth during the book. That being said the action scenes are fantastic, and the last 100 pages or so I couldn't stop reading. If your a fan of books like Clive Cusslers Dirk Pitt Series you will enjoy this book as well.
