Considering that I work on board one of the boats described in this book, I found it quite interesting.
The book begins with an overview of submarine actions during the Second World War, and then delves into the histories of the old fleet submarines that are currently museums in the United States. If you are very well versed in submarine history and lingo, these stories may seem to be lacking the level of detail that other books might. However, it does a wonderful job highlighting the surviving ships and explaining their relevance to those who haven't already studied naval history in depth.
My one gripe is an accuracy issue - the author has made some errors when referring to post war modifications, specifically a confusion between having a snorkel installed, the GUPPY modification program, and Fleet Snorkels. For the casual reader, this does not detract from the story.
