Query: Terrible book

This author is incapable of writing more than a 4 page chapter.There is zero substance to the story. The hero does absolutely nothing except travel - one has to wonder exactly WHAT does he do for the FBI. The violence is gratuitous. And to top it off, he manages to dispatch an arch villain in the space of a couple of sentences, with next to no build up to it.Can't wait for the book to be over with. If you have a choice between this and another book - choose the other!
