“Hasta La Vista, Baby”
T800, Terminator 2: Judgment Day


Court Gentry or The Gray Man is one of my favorite heroes. Court is an assassin with a conscience and once a deadly operator for the CIA. He's been on the run for some time after being framed. He now has a companion, Zoya Zakharova, a former SVR hiding from the country she served.

While Court and Zoya are staying in the beautiful but stormy Panajachel, Guatemala under new identities, Zoya's "uncle" tracks her down and pleads for her help with extracting a scientist in Mexico who's on a kill list. World-renowned robotics and AI experts are killed off one by one, professionally orchestrated by an unknown authority.

Zoya gets involved and so Court gets involved.

The Chaos Agent hooked me right from the start. I love the beginning of it and not knowing the direction of the story kept me invested. The action started quite early too so it was an adrenaline rush from early on. Although it was action-packed, the middle part gave me so much trouble keeping interest. There are MANY characters and they ended up in Cuba. Somehow the story wasn't moving forward much, it felt long. Wait, it is long ~ 560 pages. The reveal was unexpected but I should've seen it coming. I love that feeling and want to kick myself for missing it. The ending was good and hints at where the Gray Man will be in the next one. 🫨

Whoever controls the use of artificial intelligence for weapons will control the world. That simple premise is all you really need to know when you pick up Mark Greaney’s The Chaos Agent. The 13th entry in Greaney’s high-voltage, ripped-from-the-headlines action/espionage series poses the very real question of how AI will influence future wars and the global balance of power.

Artificial intelligence has exploded into the zeitgeist over the last year, a looming factor in everything from computer search engines to writing and drawing programs. So it makes sense that the threat of an AI-enhanced weapons system — “machines that think like humans, albeit better, faster, and utterly without remorse” — would be a natural lure for Greaney, who has a tendency to weave current events into his novels. The scary threat of The Terminator’s rogue Skynet AI system suddenly seems hauntingly real.

Not that Greaney’s ex-CIA operative/man on the run Court Gentry, better known as the Gray Man, is looking for trouble in his latest outing. Gentry wants no part of the mission, but when a hitman – aka Lancer, “one of the most infamous killers for hire on the planet” and second only to the Gray Man in his skills — puts him on a kill list of high-profile scientists and engineers around the world, there's no turning back.

The story culminates in an all-out battle royal that will keep readers turning pages long into the night and leave them thirsting for the next installment in the Gray Man series.

Following on the success of last year’s Netflix original movie starring Ryan Gosling, the novel is sure to attract longtime fans and newbies alike. And while The Chaos Agent includes a number of characters from Greaney’s past novels, the book is completely accessible to new readers.

As usual, Greaney — who cut his teeth writing novels in Tom Clancy’s Jack Ryan universe — also packs the novel with meticulous detail and attention to locales (many of which he has visited firsthand), weapons, and high-octane fight scenes without losing sight of his characters’ personalities and the emotional weight heaped on them.

While former intelligence officers Court Gentry and Zoya Feodorovna Zakharova are lying low in a highland Guatemalan village and assessing their options, the world's top experts in robotics and AI are rapidly being assassinated. Is a corporate entity trying to eliminate its competition, or is a government attempting to be the only one with a game-changing weapons system powered by AI?

This is a pulse-pounding, action-packed thriller with a terrifying vision of the capabilities of technology. I was grateful for a character guide that introduced the book; it was a little challenging to keep track of who each one was and what entity they were aligned with. While the book was a bit outside my normal genres, it definitely held my interest and sent me down a fascinating research rabbit hole. Lots of violence and a doozy of a cliff-hanger, but a thought-provoking page-turner.

Thank you so much to Berkley and Netgalley for this ARC to review!

Holy cow! I’m hooked. I know it’s a no no to see the movie before reading the book, but I’ve been bad. I saw The Gray Man a year or so ago and, consequently, I became captivated with the sophisticated action-packed thriller and jumped on the chance to read Mr. Greaney’s latest novel in the series.

While Courtland Gentry, aka The Gray Man, and his partner Zoya Zakharova, aka Anthem, are running for their lives from the governments they worked for, several artificial intelligence experts are being murdered one by one. And by a chance meeting with a former colleague, Court and Zoya are next.

This book creates tension and suspense from the very beginning and the idea of machines working together to destroy humans is incredible as well as terrifying. We have heard lots about artificial intelligence in the media and it’s not going away. From smart phones to autonomous Smart Cars, it’s in our daily lives, but what about our finances, our healthcare, and our defense systems? Greaney explores the idea that all of that information is dangerously floating out there in mass quantities and can be hacked and used against us in an alarming and devastating way.

It’s been a while since I read a terrific thriller and Mr. Greaney has raised the bar for me. His attention to detail is superb as he educates the reader about the ins and outs of AI while developing incredible characters who are conflicted and challenged with their morals and beliefs.

From the first nail-biting action scene to the final battle for humanity, I could not put this 556-page fast-paced book down. If you love political and military thrillers filled with gripping and chaotic action, don’t hesitate to pick up this book. It is a terrifying and tangible look into the world’s future and I’m shaking in my boots.

Thank you to Mr. Greaney for giving me the opportunity to read this book with no expectations of a positive review.

Note: I received a copy of this book in exchange for my honest opinion. Thank you, NetGalley and publishers.

The Chaos Agent is an action packed techno-thriller perfect for everyone who loves James Bond or Jason Bourne. The latest entry in Mark Greaney’s Grey Man series, like the title character himself, hits the ground running and pulls no punches. Around the world, geniuses in the world of AI are being hunted down and eliminated mercilessly, apparently by an implacable enemy with endless resources of human beings and the best equipment money can buy. And of course, Court and Zoya find themselves drawn into an increasingly tangled international web where no one is safe. Can even they make it out alive?

What with AI being so prevalent in society today the scenario and plot line of this novel is disturbing. The Gray Man series has entertained us with many previous novels, even though each can stand alone. I found this one to be difficult to get through, even though I enjoyed the beginning chapters.

There are way too many characters, locales and possibilities. The convoluted plots got to me after awhile, as did the wordy descriptions that brought nothing to the main story. I was very tempted to not finish this. I don’t want to discourage anyone from the read however, as I was reading the ARC, perhaps the publishers have refined the finished product, eliminating the frills.

Thank you to the publishers via NetGalley for the opportunity to give my unbiased review.

The Chaos Agent by Mark Greaney, is an exhilarating thriller that skillfully captures the essence of our technology-driven era. This pulse-pounding novel delves into the very heart of our zeitgeist, immersing readers in a world of relentless suspense and intrigue.

I received an ARC from "NetGalley" and I am voluntarily leaving an honest review.

The story begins with Court and Zoya laying low in Guatemala. The are cooped up in an apartment until the rain stops. The then go to a cafe to get something to eat. During their meal, Zoya recognizes an individual and returns later to talk to him. Because of this interaction, Court and Zoya get put on a kill list. Since they have not been looking at the news, they were unaware of all the people involved with AI being assassinated. An old acquaintance of Court's has been directed to take both Court and Zota out. The two manage to escape and eventually end up in Mexico where Court meets up with his old handler.

Things go from bad to worse and eventually the two team up with the CIA. Their task is to put an end to the killing.

To find out what event happened in Mexico, how the two ultimately joined with the CIA and who was responsible for the assassination and why, then you need to read this book You won't be disappointed.

Another winner in the Gray Man series. This is the 13th book in the series and they just keep getting better and better. This one has everything you want in an action thriller: great characters, a fast paced plot, and unexpected twists. Throw in some weaponized AI and you're in for an edge of your seat thriller. Highly recommended

Thanks to NetGalley and Berkley Publisher for an advanced reader copy.

A complex thriller with AI at the center of the story. A series of assassinations of top AI scientists and thinkers turns into much more as assassin is pitted against assassin. Russia, China and the US are in the running for responsibility. Lots of action and bloodshed in cinematic reading. A little too long but the many sub plots enhance the plot. Some surprises and I am in for the next Gray Man novel.

Loved this latest in the Grey Man series. It was a non-stop action read with a great story-line. Subject was AI robots and how far mankind will go to win. What would be the cost if AI machines can rewrite the codes to control them. Loved the action of Court, Zoya, Zack Hightower, and the Ground Branch men. Definitely kept me on the edge of my seat until the very end. Can't wait to read the next in the series.

Artificial intelligence is a societal buzzword. AI is the amalgamation of numerous technologies that, when successful, allow the AI agent to learn and modify its actions. The tech is so new and still scattered. Now if someone with a futurist’s vision could unify the tech . . .

Let’s say someone has kind of figured out how to integrate the tech. That might be the savior or destroyer of the world, depending on what the AI learns and applies. Let’s say there are a couple dozen different ‘modules’ of tech needed to fully realize AI’s potential. To ensure one’s place at the top of the pyramid, the geniuses behind each module would need to be eliminated.

Over the span of about 1 week, billionaire tech geniuses are dying by accident, ‘natural causes’ or just plain murder.

Courtland Gentry (aka ‘the gray man’) and Zoya Zakharova are staying a couple steps ahead of the CIA and the SVR hiding out in Guatemala. One of Zoya’s former mentors reaches out for help in guarding a Russian AI genius in transit to Mexico City, but the genius is struck down. A day before and after finds others killed in Vegas and Canada. Each hit was carried out by a highly skilled shooter who has equally skilled oversight provided by an expert drone pilot.

The video captured at the Mexico hit is sent back to a control center in Malaysia where facial recognition identifies Zoya. She is traced back to Guatemala and the AI of the control center (‘Cyrus’) decides that she and her companion need to be eliminated. A cat and mouse game ensues with the Malaysia control center following Court and Zoya.

Meanwhile, in the UK a hit on a Kiwi AI genius fails. The Kiwi, Anton Hinton, flees the UK for one of his protected labs around the world, this on in Cuba. And you can guess what happens next: Court/Zoya and Hinton kind of butt heads in Cuba. At issues is the future of the tech. Will it be used for the betterment of humanity or does it have the potential to self-actualize and run amok like Cyberdyne in the Terminator movies.

I see that this is the 13th Gray Man book produced by Greaney. We’ve reviewed a few of them here, all favorably. And this is no exception. A first rate action-thriller. The Chaos Agent is a wild ride of deception, murder, and some serious passages of action tying up multiple scenarios around just where and how AI will best be pursued. It had been a while since I last read a Greaney book so I streamed The Gray May (with Ryan Gosling). Not sure how much that helped but it did show the extent to which Greaney will go to portray action. Let’s just say, be prepared for a wild ride over the last 25% of the book.

Thanks to Netgalley for the advance reviewer copy of the book. Their website was offline for maintenance so I can’t say when in 2024 it’ll be available.

Rating- 3.75

So I’m already a big fan of Court Gentry and the Gray Man series and The Chaos Agent did not disappoint.

The Gray Man finds himself in the middle of a huge conflict between man and machine. So fitting right now with AI becoming the future, but at the same time kind of terrifying to think of what’s possible with this technology..The story line was full of action. ending was exciting and unexpected. It definitely left me wanting more.

The only con for me was that there were a couple parts in the middle of the book that were a drag to get through, maybe a bit too much tech speak.

Thank you to Berkeley Publishing Group and NetGalley for an ARC.

The Gray Man is a particular favorite in my family with my husband, adult son and I all loving his adventures and his competence. I’m not particularly interested in military equipment but I know that is a big draw for readers of this genre. The latest volume has Our Guy and his Russian spy girlfriend enjoying some downtime when they find themselves pulled into a very contemporary storyline. Someone is targeting the top minds working with artificial intelligence and killing them off . The danger with worldwide ramifications is creating a military system that by removing human decision making and replacing it with A.I., gives all advantage to the faster reflexes of A.I. Who is behind the assassinations — China, the U.S. or the military-industrial complex?
There is great strategy and lots of battles between humans and robots. In fact, the story is reminiscent of the Will Smith sci fi movie of 20 years ago, I Robot.
My only complaint is the author’s decision to end the book with a cliff hanger. I am confident any Gray Man fan will read the next book in the series and needs no gimmicks to guarantee their purchase. Instead of feeling completely satisfied with the ending of this book, I felt manipulated.

Assassin-for-hire Court Gentry (the Gray Man) and his ex-rival now girlfriend, super Russia assassin Zoya Zakharova, have been hiding out in Central and South America, enjoying downtime together and eluding both the U.S. and Russian governments who want each captured or dead.

An older ex-Russian agent approaches Zoya in a small Guatemala lake town asking for help to protect an AI engineer whose life is at risk, and suddenly Court and Zoya find themselves targeted by facial recognition software and under death threats themselves. On their trail: Scott Kincaid a ruthless assassin known by code name Lancer and also known for leaving excessive collateral damage of civilians in his killings. But ultimately compared to other Gray Man novels, Court plays mostly a secondary support role to his longtime agency friends who are on the hunt for the perpetrator of the killings.

Meanwhile, around the world, close to a dozen top AI scientists and engineers are being killed in rapid succession. Jim Pace from the CIA is tasked with traveling to the assassination sites to try to figure out what’s going on. All have some connection to the use of AI to develop autonomous weapons powered by advanced AI. This is where this novel shines: in the truly scary prospect of both the attraction of using AI to power weapons faster than humans and the potential horror of something going wrong with the AI in control. The killings feature robots that look like Greyhounds with rifles affixed to the backs and endless variations of drones ranging from barely visible to those carrying powerful detonation payloads.

In charge: some combination of famous billionaire Anton Hinton who claims he has a vision of world peace and an AI that Hinton’s created named Cyrus who may be behaving erractically. But Hinton may also be angling to sell his new AI weaponry to the highest bidder, which appears to be China. But, the U.S. wants the technology for themselves. Thrown into the mix: an old favorite Zack Hightower who’s been drawn out of retirement to take control of Hinton’s security team.

All action leads to Cuba, where Hinton has converted a sprawling old Russian intelligence campus and bunker into his AI lab. The tension keeps ratcheting up, and ends in non-stop violence between CIA teams, Hinton’s private security, AI driven autonomous weapons, and the Cuban militia that went on for so long that that it ultimately seemed gratuitous and over the top. I found myself skimming dozens of fight pages.

But gotta love Greaney for a huge, cliff-hanger set up for the next outing in this series, where Court and Zoya will return to the forefront.

Thanks to Berkley Publishing Group and NetGalley for an advanced reader’s copy.

The Chaos Agent

As is often the case, Mark Greaney is on the forefront of topical issues with this one. You have artificial intelligence that starts out promising but is soon running amok, advanced drones capable of doing amazing things, and a seemingly benign tech guru who is, under his veneer, pretty reprehensible. All of this presents quite a challenge for the Gray Man, but with a little help, he is up to it.

This one has what Gray Man fans have come to expect: fast-paced action with high tech weapons and compelling characters in various exotic locales. As usual, this offering from Mark Greaney is escapist espionage fare at its finest.

I am grateful to NetGalley for the opportunity to read this novel in exchange for an honest review.

Mark Greaney's The Chaos Agent (Berkley 2024), Book 13 of Gray Man series, is another winner. This one is ripped from future headlines about the power of AI. Against his better instincts, Court Gentry, aka, the Gray Man, is pulled into an international battle to control AI warfare and those who know how to invent and run it. The major players in this industry on the West's side are being killed off, leaving the Chinese scientists to continue their work unchallenged. Except there’s a problem. One of the murdered players in this industry is personal to Gentry's girlfriend, Zoya Zakharova. Because she is close to this man, the killers think they must eliminate her, which Gentry won't allow. While the killers try to figure out how to deal with Gentry and Zoya, their mostly-unchallenged AI is learning how to dominate the world and wrest control from its human masters. As Gentry tries to save Zoya's life, and his own, he is also fighting for the survival of humanity in a Wild West of Man vs. Machine. 

The only downside of this book is that Greaney includes an awful lot of background on the characters. It’s interesting and builds their credibility, but slows the plot. It took a long time for Court and Zoya to get from their Guatemala hideout to the story's climax locations as Greaney was building all of this backstory. Not good or bad. Just a comment, and having said that, I still couldn't stop reading and gave the book an enthusiastic 5/5.

Five stars! Unputdownable! The Chaos Agent is not my usual genre, but I loved it. It's action-packed with AI military-grade weapons. Although I could predict some plot points, it contains some great twists. It was a fantastic read.
Thank you @netgalley and @berkleypublishing for the eArc! #thechaosagent

This is a can’t put down non stop action book. The story is fast paced and grabs you from the first page. This book is part of a series and could be read as a stand alone, but the series itself is so good I recommend all of them. Thank you to net galley for an advanced readers copy.

Another bombtastic addition to the series!
~~~~~~~~~~
If you love fast-paced reads that make you question everything you think you know about world politics and players, this is the book for you.

Greaney cannonballs us right into AI for military use and its full attempt to start a world domination plot. Buckle up for this ride that is nothing short of scary and crazy!

All of the main players are included in this edition; Court, Zoya, and Zack, plus so many more that you will recognize from other books. The interactions are wild and unbelievable! And hang on for the messed-up twist at the end that plows us right into the next book.

If you are looking for a methodical thriller and suspense-type espionage story, this is not it. Greaney packs in so much action and twists that you need to clear a weekend for this book. Once you start reading, it is tough to stop!

The Chaos Agent is controlled chaos throughout and you will not want to miss this one!
