A fair to middling submarine adventure. I wasn't really a fan of the main character...I didn't really like the side mission his, apparently super-spy wife, was engaged in across the world. Winning over the Soviet crew seemed entirely too easy...
...and this book was published in 1992, but there's a Soviet Union...and it's not alternate history, near as I can tell.
A lot of this novel was the main character and his wife working through their emotional damage so that they could have a touching reunion in the end. Mayhaps if I didn't jump into this story in book three and had started in book one, I'd care and/or be invested in it...but coming into it with little to no background just made them both seem like whiney crybabies...
But, the main action is onboard a Russian submarine...an old Victor II...which doesn't seem to be a hindrance in 1992...but, still fun. :)
The cover isn't really related either. There are Los Angeles-classes in the novel, but in the background...and the Kentucky isn't a DSRV, so it being piggybacked doesn't really fit...but, it's an "exciting" action shot, I guess...
