Query: What A Page Turner!

My favorite books of Nelson Demille's have been, up to this point, the Gold Coast and Plum Island. Now Up Country has surpassed both of them. If one likes adventure and is quick-witted at all, how can you not like this book? The characters seem real and what an amazing travelogue. I wish he would release 12 books a year. Don't miss this book!
