Query: Not that great

I picked up this paperback in the airport while my flight was delayed and had high hopes for it.Like most have already said, the first half of the book looked good, but fell apart at the end.This was the first book I have read by Mr. Martini and may be the last.If you like this sort of book, go for David Baldacci instead.
