This was a FUN book! The narrator did an AMAZING job with the various voices and the accents. I’ve found a new favorite author and narrator! I almost became a naval submariner myself, so the descriptions of life on a submarine were even more fascinating to me! I also watched the Call of the Wolf French film on Netflix halfway thru reading/listening to this book which gave me an even better understanding of life aboard a cramped submarine. If you like suspense, horror, and military themed novels then THIS book is for you!!
