The story of a onetime CIA assassin who is now doing work for hire, meanwhile dodging the assassins who replaced him. While he is a killer, his personal code—for one thing, he only takes out those he considers truly evil—makes you, somehow, improbably, root for him. And the action, the twists, the turns, the writing…everything is dazzling. Greaney’s enthusiasm—no, love—for the subject matter is readily apparent. And infections. In the past ten years, in addition to ten Gray Man novels, he has also written a good half-dozen thousand-page Tom Clancy novels, among other books, in each case traveling all over the world for research, and, consequently, it is as though each novel comes with a free James Bamford book. For writers, Greaney is simply an inspiration.
