Description

The Gray Man, the world’s deadliest assassin and apex predator, discovers he’s really the prey in the most shocking entry of this #1 New York Times bestselling series.

Family means different things to different people, but in the Gray Man’s world, family is defined by blood—the blood you share with some and the blood you shed with others.

Court Gentry’s current family operates out of an office park in Norfolk, Virginia. The Ghost Town is an off-the-books direct action team run by Matt Hanley, former CIA Deputy Director. They take on the jobs the Agency needs handled “discretely,” and those jobs are rolling in.

Somewhere at the top of the US Intelligence apparatus, security experts and intelligence operations worldwide are threatened. 

It starts with a blown safe house in Tunis. Then Court himself barely escapes from an ambush in the jungles of Nicaragua. Now key members of the U.S. counterintelligence community are being assassinated in their own neighborhoods. With the feds compromised, it’s up to Court and his team to stop the hit squads. 

But eliminating professional kill teams may be the least of the Gray Man’s worries when he finds himself targeted by the legendary assassin codenamed Whetstone—a man driven out of retirement by a very personal quest to rain down hellfire on Court and everyone he’s ever loved, starting with the father he hasn’t seen in twenty years.

    Well done. Don't usually like books over 1000 pages but this was so well written I wish it was longer.
  • Exciting read

    Maybe my favorite in the long series. My only complaint- not a great time to be associating ICE in any way with the main characters of the series. And, hopefully that segment was not meant to be humorous on some level. Unless, of course, your target audience is xenophobic conservative dudes.
  • Another Great Read

    I just finished Hardline by Mark Greaney and honestly couldn’t put it down. If you like fast-paced thrillers with a lot of action, this one definitely hits the mark. The story moves quickly but never feels rushed, and there are enough twists to keep things interesting the whole way through. Court Gentry (the Gray Man) is as sharp and capable as ever, and it’s fun watching how he navigates situations that seem impossible to get out of. One thing I really appreciated was how real everything felt. The details, the settings, and the action scenes all seem well thought out without getting bogged down or overly technical. Overall, it’s just a really entertaining read. Whether you’ve followed the series for a while or are jumping in for the first time, this is a great one to pick up.
  • Possibly the Best Book in the Series

    This book started off a little slow. Then it picked up. Then it really picked up. So many twists and turns. As a former Special Operator I found the author’s knowledge of weapons and procedures amazingly accurate. I myself carry a Stacatto C2 and consider it the best everyday carry handgun. The ending was a total surprise and the best part it left room for the Gray Man to return.
  • Not up to par!

    Horrible ending. Plot had with more holes than Swiss cheese. Formulaic. Uninspired. Very disappointed.

    Finally, a return to the great of this series and not the lovestruck teenager angst. The ending wasn't great, but this is top 4 in the series.
