Query: weak writing, weaker plot

Baldacci's writing style is on a par with that of a skilled high schooler. What has made his books enjoyable to read is his imagination and interesting plot lines. This is one you'll completely forget in a week. Either he has run out of interest, or is tired of putting in the necessary work to write a better book. Your time would be better spent finding a Scott Turow novel you haven't read.
