Sierra Six

By Mark Greaney

Categories: Mystery, Thriller & Suspense

Mark Greaney's eleventh Gray Man novel moves between two timelines. In one, a young Court Gentry, code-named Sierra Six, is the junior member of Zack Hightower's CIA paramilitary team, Golf Sierra, on a mission against terrorists in Pakistan. In the other, twelve years on, Gentry is on a simple job when he spots a terrorist leader he believed long dead, and resolves to settle a blood debt as the man prepares an even deadlier version of his earlier plan.
