Query: This book is a must-read! Extremely interesting.

On a personal level, my father - John Allen Wilson (referred to in the book as "Tugboat Wilson"), had talked about the happenings in this book as I was growing up, but I did not become interested in it until after he had passed away. I have pictures that he sent to his sister of the ship during the operation that were given to me. The pictures, along with the memories of the stories from my childhood, encouraged me to seek out and find copies it. Not only was I able to find a few copies, I was able to acquire an autograph copy by the author. I was not disappointed. It is a very poignant and inspiring account of the life of an era gone by (the hard-hat diver).
