Mission Critical
Court Gentry's flight on a CIA transport plane is interrupted when a security team brings a hooded man aboard. They want to kick Gentry off the flight but are overruled by CIA headquarters. The mystery man is being transported to England where a joint CIA/MI6 team will interrogate him about a mole in Langley.
When they land in an isolated airbase in the U.K., they are attacked by a hostile force who kidnaps the prisoner. Only Gentry escapes. His handlers send him after the attackers, but what can one operative do against a trained team of assassins? A lot, when that operative is the Gray Man.

Mark Greaney
Long before The Gray Man was a global bestseller—or a Netflix action juggernaut—Mark Greaney was immersed in the world of shadows, diplomacy, and high-stakes espionage. What sets him apart isn’t just the precision of his plots or the grit of his protagonists—it’s his ability to make readers feel the tension of a sniper’s breath, the pulse of a tail through foreign streets, the weight of impossible decisions in murky moral terrain.
Greaney didn’t stumble into the thriller world; he stormed into it, notebook in hand and adrenaline in his blood. Raised in Memphis, Tennessee, he studied international relations and political science—fields that now pulse beneath the surface of his fiction. He took those early academic roots and grew them into stories that feel frighteningly plausible, weaving real-world geopolitics with explosive action. It's no wonder Tom Clancy's estate tapped him to co-write (and eventually continue solo) the Jack Ryan universe—a handoff that could’ve gone wrong in less capable hands but flourished under Greaney’s.
Gray Man
In the covert corridors of global espionage, there’s one name whispered more often than most—not in admiration, but in warning: the Gray Man. Court Gentry isn’t a hero in the traditional sense—he’s a shadow that moves when the lights go out, a former CIA operative turned freelance assassin, navigating a world where loyalty is currency and survival is a skill honed to perfection.
Gray Man consists of fifteen books and series is set to expand with the upcoming release of two more books. The current recommended reading order for the series is provided below.
