The Gray Man is an assassin with principles. He kills the bad guys. He kills in self defense. He makes the impossible possible. He is one real cool customer. And at the same time he himself is being hunted down to be killed by other government agencies (USA is the lead hunter). This book is the SECOND of five of Gray Man novels. I've read all five. Greaney really does in depth research for all of his books. Greaney goes all over the world looking, talking, interviewing to really add a "now" reality to plot Gray Man's weird look at the life he leads. And and all the twists and turns that happens...you'll find yourself with five or six pages to finish and Greaney hits you with twists. When you read about The Gray Man, his story ain't over until it's over.............................................Be sure you start with book #1 (The Gray Man) then in sequence to book #5 (Back Blast).
