Sierra Six

It's been years since the Gray Man's first mission, but the trouble's just getting started...

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.
