It's been years since the Gray Man's first mission, but the trouble's just getting started in the latest entry in the #1 New York Times bestselling 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, but at a terrible price—the life of a woman Court cared for. Years have passed and now 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 may have gone by but the Gray Man hasn't changed. He isn't one to leave a job unfinished or a blood debt unpaid.
