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, 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.
"Sharp, cinematic, and packed with action—the Gray Man novels blow all other thrillers away!"
—Brad Thor, #1 New York Times bestselling author of Black Ice
"Excellent....Greaney seamlessly adjusts focus between the timelines, jumping from one exhilarating roller-coaster ride to the other. Spy and military thriller fans will be well pleased."
—Publishers Weekly (starred review)
“Greaney hit absolute literary gold with his Gray Man series…and Sierra Six is no exception!”
