Query: Very Disappointing

I am a self admitted Tom Clancy junkie and had read all of his books, with SSN being the sole remaining piece. I am quite frankly having a difficult time believing that Tom Clancy actually wrote this book. While there are some very fascinating peeks into the inner workings of a submarine, the book is repetitive to the point of boring, has unrealistic and not believable fiction. Each of the battle sequences seems to be the exact same, with minor variations. The fiction regarding the location of the legal Chinese PM, the response of the Chinese people to the naval conflicts, and the method of transportation for the Chinese PM back to resolve the conflict are down right silly. Unless you really really really want to know some random facts about how a Submarine works, I would advise avoiding this book.
