Mark Greaney Books in Order

Mark Greaney is the New York Times bestselling author of the Gray Man, aka Court Gentry series, featuring Courtland Gentry, former CIA operative and current assassin often hired by various government agencies including the CIA to take care of business where official government operatives can’t. Court is very good at his job and he blends in so well that everyone knows him and fears him by the name of The Gray Man.

Many readers know Mark Greaney, however, for his contribution to the Jack Ryan Universe started by the bestselling author Tom Clancy who passed away in 2013. Mark wrote several of the novels starting from 2011 Locked On. I personally know readers who have moved on to Mark Greaney’s novels in the Gray Man books after reading some of his Jack Ryan novels.

Here are the Mark Greaney books in order for his two series, with the list updated as soon as we know of new releases.

Who Is Court Gentry?

Court Gentry, aka the Violator, aka the Gray Man, is an action-oriented guy. He solves most of his problems using guns, which is what he knows best. He isn’t one for affection, and he would never get himself a pet. For Court it’s easy to switch off his emotions to get the job done, which in most cases is kill a mark.

In Court’s world, there are no clear black and white colors. Everything is a shade of gray. Even the bad guys have their reasons for doing their bad things, and Court himself is not the white knight in shining armor either, and he knows it.

Court Gentry was once a CIA agent who fell out of grace and went on solo. Not only that, but the CIA wanted to have him killed, all due to a misunderstanding. Eventually, their relationship was sort of mended, and in the later books, the Gray Man takes on and off jobs from the agency as well, for which he is a deniable asset.

The Gray Man is one of the – if not the – best assassin in the world, which all enemies fear.

Mark Greaney Biography

Mark Greaney (Mark Strode Greaney) was born in 1967, Memphis, Tennessee. His father, Ed Greaney,  worked at Channel 5, WMC-TV Memphis for over 50 years where he was a general manager. During WWII, Ed Greaney was an infantry sergeant in Germany and the Philippines.

With his family, Mark traveled quite a lot, and as his father was always interested in current events, and was reading a lot of books, Mark inherited that love of reading from a young age. He read many books, including WWII books, spy books, crime books, even books about James Bond. Also, he wanted to write stories already as a child, and with his love for thriller and crime books, he would always want to write novels in his genre, which is something he eventually did.

Mark attended the University of Memphis, from where he earned a degree in international relations and political science.

He worked on his first book for several years, but when it was done, he was not very happy with it. So he wrote a second one which he decided to have published. He searched for the agent who also worked with one of Mark’s favorite authors, Ralph Peters, and eventually managed to catch the agent, Scott Miller, during a conference in 2006. He gave the agent 20 pages of the book, and Scott told him that he would work with him but on another book, not on this one.

So Mark set up to write a third book, which eventually became The Gray Man, to be published in 2009 by Penguin, who immediately commissioned two additional Mark Greaney’s novels. The novel became an international thriller loved all over the world.

In the meantime, he also agreed to work with Tom Clancy to ghostwrite two books, which would become Locked On and Threat Vector in the President Jack Ryan series. This was just before Tom Clancy passed away in 2013. Soon, however, Mark Greaney wrote several additional Jack Ryan books, all the way to 2016 with True Faith and Allegiance. While he currently stopped working on more Jack Ryan Jr. stories, he still continued writing his Gray Man series.

At some point, Mark Greaney went through several back surgeries and he had to take a lot of pain medication. This, somehow, translated into part of the story in On Target, which picked up several months after The Gray Man books ended. Here Court had his own surgeries, and while most of his pain was over, he still suffered from them occasionally.

For research on his books, the Gray Man author has done a lot of traveling over the years, including to Mexico to research drug cartels for Ballistic, the third Court Gentry book, for example. He also traveled several times to Guatemala, and he lived in Germany after he graduated from college for a few months. He also traveled to various other parts of Europe.

For his book research, Mark has extensively traveled to numerous countries, including visits to the Pentagon, military bases, embassies, and intelligence agencies. Additionally, he has undergone training alongside military agencies and law enforcement personnel as part of his research for his works.

In addition to his national bestseller Gray Man/Violator series and his contribution to the New York Times bestselling President Jack Ryan and Jack Ryan Jr. series, he also co-authored a standalone thriller novel with decorated United States Marine Officer, Lieutenant Colonel Hunter Ripley Rawlings, titled Red Metal, a book that was released in 2019. He first met the colonel  at the Pentagon while doing research for Clancy book several years before.

His latest series features Joshua Duffy, one of the world’s elite operatives with a reputation that sets him apart in the field of personal security and high-stakes missions who becomes a Close Protection Agent, which is another term for a professional bodyguard.

In terms of the book-to-movie translation, many fans have been waiting for years for a Gray Man movie. 2022 saw the Netflix adaptation of The Gray Man books, starring Ryan Gosling, Chris Evans, and Ana de Armas which was released in July.

Mark lives in Memphis, Tennessee with his two Catahoula Leopard dogs, Lobo and Ziggy, while he is working on his next novel.
