From Mark Greaney, the New York Times bestselling author of Gunmetal Gray and a coauthor of Tom Clancy's Jack Ryan novels, comes a high-stakes thriller featuring the world's most dangerous assassin: the Gray Man.

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.


  • Gray Man Lives To Fight On For Both Good & Evil

    By Late Night T43
    This is a classic Mark Greaney novel with just the right amount of suspense and probability to keep you turning the pages and staying up late to see how the good survive and the bad guys are terminated. The only problem is that each book seems to get longer and more complex with side stories.
  • Best action series.

    By GBell$
    One of the best action books I have read during COVID lockdown.
  • Exciting Fast Pace

    By Guppa59
    The flow of the story is fast paced as usual. However, I recoil at typos which there were many. I also have a tendency to fact check locations and hardware. I found many issues in this story where the author took liberties with location names. While I understand this is fiction, I believe the writer could do a great deal to add truths to support his story. I’ve read all of this series and will continue to do so. Still a very exciting read.

    Love the dynamic with Court and Zoya. The unexpected with Brewer, and the addition of the other Ground Branch operatives made for a great read.
  • Great read

    By Jared Bays
    Best one yet!! Ive read all 8 books in The Grey Man series and this one takes the cake.
  • Meh

    By Longhorn5555
    Started off strong but then just meandered into stupidville. The entire premise for the villain, whose “logic” swings back and forth between silly and inconsistent, is better suited for an Austin Powers movie. About 60% through I found myself skipping pages over and over, until finally, at what presumably was the action packed climax, I found myself so bored with it that could care less what happened. Come on author, put a little effort into it, or price it for the silly pulp fiction it is. And this is from someone who enjoyed some of your earlier efforts...
  • He mailed this in or someone else wrote it

    By JMcanam
    Not at all worth it and I have read and enjoyed all his other books. Was difficult to get involved with the story
  • Mission critical

    By Bavarian Hillbilly
    Another great gray man novel. All eight books have been terrific. Mr. Greaney sir; please keep Zack and Zoya in future writings. The three of them make a great team.
  • Mission Critical

    By Ghostrover78
    Explosive read out of the gate. The Gray Man in ‘Mission Critical’ does not disappoint. A nice change to read Court’s physical prowess being truly tested by Hines. Strong woman in Zoya. Hopefully future escapades of The Gray Man will include from time to time Zoya and Zach. Great work again Mark Greaney.
  • Outstanding
