This is the gold standard of cold war naval politics. I recommend the reader to watch the movie too. Most interesting to me are the personalities of Marco Ramius, Jonesy and Manusco. Although Ryan is the reason the story unfolds all the military, executive and diplomatic characters so perfectly depicted by Tom Clancy is the reason that makes the story so great. Tom Clancy also shows the reader the details of the SOSUS network and the skills and risks of submarine navigation.
