Yes, it's a fast paced action thriller but the plot is so contrived and implausible and the characters are nearly all so stereotyped and unlikeable that well before half way through I was getting bored with it.
It contains so much of what is worst in American crime / thriller writing. The central character, Secret Agent Will Robie is depicted as an all American hero who almost single handedly defeats a bizarre terrorist plot. What a guy! Sure, he gets some help from a female FBI agent who also seems willing to put her own and other people's lives at risk, so, hey, she's cool too! They "gun" engines, do donut turns, run red lights etc and when they face gunfire from well trained and well equipped adversaries they are seemingly protected by a magical shield whilst death and destruction explodearound them. You get the picture.
And despite a bus full of passengers being blown up and numerous other murders being committed it seems that the FBI agent is the only person officially on the case. Nonsense, of course but it creates the vacuum of reality which allows Baldacci to hype up his hero.
No doubt this storyline would make for a half decent action movie but for me it just doesn't work as a book. It is one shallow chapter of contrived action after another and it simply gets tiresome.
