Publisher's Summary It's been years since the Gray Man's first mission, but the trouble's just getting started in the latest entry in the number one New York Times best-selling series. Before he was the Gray Man, Court Gentry was Sierra Six, the junior member of a CIA action team. In their first mission, they took out a terrorist leader, at a terrible price. Years have passed. The Gray Man is on a simple mission when he sees a ghost: the long-dead terrorist, but he's remarkably energetic for a dead man.  A decade of time hasn't changed the Gray Man. He isn't one to leave a job unfinished or a blood debt unpaid. ©2022 Mark Greaney Books LLC (P)2022 Audible, Inc.
