The thing I remember most about this book is the heroic American Mary Sue rescuing an Icelandic damsel in distress from a traumatic sexual assault by Soviet soldiers, and then immediately afterwards she falls in love with him and they have sex in a hot spring or something. Standard conservative male military-nerd wish-fulfillment pulp fantasy written by a guy whose main protagonists are all thinly-veiled self-insertions.

That said, as a fellow nerd, I love it when Clancy tells me all the little details about a submarine, and it’s a fun read. But I wouldn’t call it good.
