This book feels very much like a "real" look at what life on a submarine is like. Power struggles, personality conflicts, good sailors and bad, etc. The USS Providence is ordered into Indonesia, turning around to go back to sea when she was supposed to be done with her voyage. Her mission is ostensibly to rescue an American humanitarian doctor, but the peaceful island of Bunda is swept up in a revolution that consumes all of Indonesia. Some of the sailors are on shore retreiving the doc, and the rest have to contend with a rebel submarine built by the Germans.
The book started slowly - a little too much "what it's really like" but then after the setup, things got really good. The end felt a bit rushed but overall it was a good read.
