Threat Vector by Tom Clancy and Mark Greaney is a great addition to the Jack Ryan series. In this novel, Jack Ryan is serving his second term as President. Jack Ryan, Jr. still works for the Campus which is a secret operation created by Jack Ryan in his first term as President to combat terrorism. The term “threat vector” refers to computer security and the possibility of a computer breach. In this novel, China is using cyber warfare to expand its empire and to try to defeat the United States.
Threat Vector is one of the best Tom Clancy novels that I’ve read in quite a while. There was plenty of action with twists and turns along the way. The plot felt “real.” In other words, it’s not hard to believe that the computer networks of the United States government could be attacked and controlled by a foreign power. Threat Vector brings back many of the characters that we’ve met in previous novels including John Clark, Domingo Chavez, and Sam Driscoll.
I have read some other reviews of this book. Most of them are positive. However, they did point out some major mistakes that should have been caught. In earlier novels, Jack Ryan, Jr. has an older sister named Sally. In this novel, Jack Ryan, Jr. is mentioned as the eldest child of the President. Also, the middle name of Chavez’s son has changed. These mistakes aside, Threat Vector is an enjoyable read from start to finish.
