Shadow Divers by Robert Kurson tells the true story of two American wreck divers who discover a sunken U-boat off the coast of New Jersey where the historical records say none should exist. Over the course of several years they risk death (at least three other divers die while exploring the U-Boat) and their marriages searching for the identity of the U-Boat, both underwater and in historical archives.
Robert Kurson makes this historical narrative an exciting story in addition to being a very well researched piece of true history. If you are interested in WWII or Scuba Diving I strongly recommend this book.
Literary Quality: 8/10
