Robert Kurson
Shadow Divers is a gripping non-fiction book that recounts the true story of deep-sea divers, John Chatterton and Richie Kohler, who discover a sunken German U-boat off the coast of New Jersey in 230 (70m) feet of water. For the non-diver reader, the limit of recreational/sport diving is 132 feet. At such depths, no diver is impervious to nitrogen narcosis, aka rapture of the deep. These daring divers were wiling to risk everything to discover the name and history of the mystery submarine lying at the bottom of the Atlantic. A ship that, for all accounts, shouldn't even be there.
Kurson masterfully combines history, adventure and the human spirit in an engaging exploration of the underwater world. This book is so well-written and descriptive that you feel like you are diving right alongside the divers as they delve deeper into the submarine seeking to solve the mystery!
