Shadow Divers

The book started slow with what I thought was an overly-detailed description of the diving process, but as I got into the book I realized the importance of laying that foundation. I enjoyed learning about the mystery of the sub, the “treasure hunt” for an identity, and the tenacity of John and Richie. I admire their passion. Not surprising but very interesting were the incorrect historical reports (and probable reasons why they were incorrect) regarding WWII subs. You can't always take history books at their word...
