"It has been so nice to find out about British submarine operations during WW2, and especially the exploits of the crew of Unbeaten. A well thought out and well written book that includes letters and messages from the crew members (one of whom is related to the author) it is a great story, almost hard to believe that it is all factual, but along with a lot of actual accounts of wartime actions it reads like a Hollywood blockbuster".
"Which brings me on to the ending, I don't mind that the end of the book has been made up, it has to be as no one knows what happened to the Unbeaten and while the way the book closes is certainly believable there is something that jars me, I would have preferred a summary of what is known rather than the speculation. But that is my niggle and entirely why it lost a star. For anyone wanting to learn more about the Allied submariners of WW2 this is a very interesting read".
