Sierra Six

Before he was known as the Gray Man, Court Gentry operated as Sierra Six, a junior member of a CIA action team. His inaugural mission, though successful in neutralizing a terrorist leader, came at the devastating cost of a woman he cared for. Years later, a seemingly routine assignment brings Gentry face-to-face with a man long believed dead—the very terrorist from that fateful first mission, now remarkably alive and active.
