content: This is the best book written by Clancy, however, Jack Ryan is nowhere in this. There are several references to "the president", and only one time do they actually say "Jack" in this.However, what makes this book the best is that it would be so easy for someone todo something like this. This is definatly Clancy at his best. Clark and Chavez definatly bring it home in this. Its a very long book, but it is a page turner. Great novel for anyone who wants some excellent reading.
