If you know "Jack Reacher" from the excellent Lee Child series of novels, you'll know everything you need to know about John Puller, the hero in this novel. He has the same courage, experience, and military training. You are seamlessly taken into his world, as he tries to put together the puzzle pieces and solve the murders that have taken place. This book was every bit as good as the Reacher series, and I couldn't put it down from page one. Bravo Baldacci! I can only hope that this is the first in a series of John Puller novels.
