My reading tastes have always been fiction: action, adventure, thrillers, and since going away to college two years ago I have not had time for any fun reading, But started this book last week and then could not put it down. It is TRUE action adventure!This is the story of two deep sea wreck divers who dive into a long lost wreck in over 200 feet of water, which they identify as a German U-boat. The book follows the lives of these two men as they attempt to discover the identity of the U-boat and discover things about themselfs. There lives are greatly changed by the discovery, Jobs changed, marriages lost, diving companions killed on the wreck, and lost to the bottle.The story is more than just about the men's dives on the wreck and there attempt to discover its identity, and the adventure involved in such an endeavor, but also about the characters (which are rich in this story) involved, the history behind the boat and Hitlers 3rd Riech. there is so much to learn on every page. In the end though it is the under water action that kept me enthralled. If you read this book you will gain an appreciation of the wonders and dangers of deep water diving.
