Query: Baldacci Wrote Half a Good Book

But the second half is pure bad. We have a good idea here, but David Baldacci couldn't figger out how to carry off the one critical ingredient of a good thriller... making it believable. You will need a large notebook just to write down all the inconsistencies and dumb ideas that he uses to piece this book together. Finally you will become irritated by all the little stupidities his hero and heroine continue committing. Still, you can move to the last chapter or two to discover how it ended without missing any of the previous 250 pages.
