Years have passed since the Gray Man's first assignment, but in the most recent book in the #1 New York Times bestselling series, the danger is just getting started.
Court Gentry was Sierra Six, the junior agent in a CIA action squad, before he was the Gray Man.
They killed a terrorist commander on their first mission, but at a horrible cost: the life of a woman Court loved. After many years, The Gray Man is now on a straightforward errand when he meets the ghost of the long-dead terrorist—who is surprisingly animated for a dead man.
Even after ten years, the Gray Man remains the same. He never abandons a task uncompleted or a debt of blood unpaid.
