Author Tom Jacobs was the XO on the USS Sargo SSN583 when I was COB. He also was the Commanding Officer on the USS Seadragon SSN584. The book's back blurb makes a true statement "Don't pick his book up at bedtime if you need your sleep". It is indeed hard to put down once you start to read this book. Go to Tom's Web site where you can read the First Chapter of Sons of God and order the book. http://www.mymysterynovel.com/ Donald E. Cole RMCM(SS) Ret
