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。
