Query: Disappointing

Very disappointing, in fact. First of all, this book is HUGE and you need a notepad handy at all times, in order to be able to follow the plot. I agree that the book sounds like a family reunion, but what the heck happened to Jack Ryan? From a believable and likable guy, he became a foul-mouthed wimp! I am sure that POTUS does not need to use language like that to get his message accross. As far as the ending goes, what happened? It looks like TC ran out of paper/memory/patience and just stopped. Or he decided to end our misery?This is not even close to his previous books. A thoroughly disappointing read, especially to all Jack Ryan fans, who anxiously waited to see what happened next.
