If you enjoy naval or general military history, this is the book for you. I consider myself generally familiar with WWII history, but I was amazed at how little I knew (or how much I had forgotten) about the submarine war in the Pacific. From O'Kane's and his skipper peers' formative years, to the evolution (or not) of submarine stategy and tactics, to the problems with torpedo malfunctions... it is all here. And what a guy Richard O'Kane was. He was a giant among heroes. Fine narrator, too.
