This is a great book so far. I am a little farther than halfway into it and it is great. Although the writing is a little choppy at times, it is definitely worth it.

This is one for the hard core action fans. There's very little 'down time' to run for popcorn. If someone isn't getting shot, punched, etc. things are getting blown up or sunk in water. There is an action scene I haven't seen yet with a police car. Several of the action scenes are worth a rewind and I did appreciate the 'buff bodies'. You have to give these guys an A plus for working out.Chrissy K. McVay - Author

Jack Polidoro has a writing style that will keep you turning the pages. This book is a fast read. The plot is exciting and moves. Jack has a way of making the tale come alive in your head. This book should be made into one of those disaster movies starring George Kennedy. It would be a knock-out! Jack included a generous helping of juicy sex too.
