About this listen

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.

The worst part about being addicted to the Gray Man books is waiting for the next book release.
Mark Greaney’s writing skills easily place him at the head of this genre and Jay Snyder is the perfect match to bring the characters to life.
Sierra Six is both a powerful and compelling story that will keep you awake late at night right up until the last chapter.

Another Gray Man classic

Another great book with duel stories. Great mixup with a past event coming to arecent event. To hear the reason of how the Goone squad come about.

Two books in one, dual story’s

Pity the Author also now started to use THE LORDS'S NAME in vain. What is it with the story that you HAVE to use God's Name to give the character "personality"? The previous Greyman novels were perfect without such language, why start using it now?

Great book.
