Scuba diver or not, this book will take you 250 feet below the surface, on a journey of suspense. Based on a real life story, you'll come to learn more about wreck diving icons, John Chatterton and Richie Kohler, as well as the perhaps infamous captains of the charter boats that take them out to the wrecks: Steve Belienda and Bill Nagle. Loved this book. Absolutely loved it.
