The cost is 20 pounds British Sterling, but that converts to approximately $34.93 US dollars including shipping. I've attached an image of the UK cover to the post. David has previous books out about the Hood and Bismark from World War 2, and the Sydney, an Australian vessel sunk by the Germans. I have both of these books and they are fascinating reading. You get a perspective from David not only of the ship discoveries, but of the day to day events on board a survey vessel. This includes all the things that can go wrong and many human stories of the crew. He's an engaging and interesting author (not just kissing up here David), and is the same in person. To truly understand all that happens on a large scale expedition, these books are remarkable. I expect nothing less of The Shipwreck Hunter.
