I didn't enjoy this one so much. The computer part lacked plausibility. The characters responded casually to things like nuclear threats and impending war with other Countries. The book makes our military sound unprofessional using slang for everything, and witty remarks in crisis situations. Not very plausible. And the F bomb, get ready for it, dropped many more times than military bombs in the book. Gd this, Gd that, the language sounded like a disgruntled teenager. This is only my 2nd Clancy book, I'm not very impressed.
