Great story that takes you below the waves and into the adventure.

Hands down, one of the best books I have ever read. As a recreational diver, I appreciated the detail of deep wreck diving. The authors writing style made this story come alive! Incredible job! I intend to research other books this author may have written! Thank you for the journey you took me on.

A rich, well-told account of the discovery, exploration, and documentation of the unknown wreck of a WW II U-boat off the coast of New Jersey. Definitely worth reading if you’re interested in quests, extreme sports, the sea, diving, or history.

Having started scuba diving at an early age and gone through the trials and tribulations of learning more less the hard way and always wondering about wreck diving and deep diving but never really having the guts to do it, I have shadow divers as my window to that particular experience. And after reading the book I don't have any regrets for not following that path, but the book was so excellent both in the writing and the story, I had a hard time setting it down. If you enjoy adventure, some technical writing and the unknown, I would strongly suggest this book. It was well worth the purchase although It was a Valentine's Day present for me. Gracias Mi Amor. And thank you for a great read Robert.

Very well written book that combines both historical facts and elements of adventure. The author did extensive research into u boats and is evidenced in the detailed facts in the book.

Excellent book. Research is amazing. True accounts from reliable sources. The author really took his time to gather all the information. Very well written and great read. If you like scuba it is a must. If you don't you will highly enjoy the book as well. Five stars!

I you enjoy diving, adventure, history, WWII, the truth, or stories of men of character, this book will barely leave your hands once you start to read.

Great read. Good mix of history and mystery.

The book is an outstanding insight to the world or Tec Dining that will keep you on the edge of your seat. If you know John and Richie like I do, or have seen the show "Deep Sea Detectives", the history makes it all come together. Well written book. AAA+++

A tremendous read for any fan of diving, history or just good non-fiction. Beautifully written and well paced. Don't miss it.
