Publisher's Summary

The Gray Man's search for missing intelligence agents plunges him deep into a maelstrom of trouble in the latest entry in the number-one New York Times best-selling series.

The first agent disappearance was a puzzle.

The second was a mystery.

The third was a conspiracy.

Intelligence operatives around the world are disappearing. When a missing American agent re-appears in Venezuela, Court Gentry, the Gray Man, is dispatched to bring him in, but a team of assassins has other ideas. Court escapes with his life and a vital piece of intelligence.

Meanwhile, CIA agent Zoya Zakharova is in Berlin. Her mission: to infiltrate a private intelligence firm with some alarming connections. The closer she gets to answers, the less likely she is to get out alive.

Court and Zoya are just two pieces on this international chessboard, and they're about to discover one undeniable truth - sometimes capturing a king requires sacrificing some pawns.

Action Packed Thriller!!!!

The title is very fitting for the tenth Gray Man book. In this book the Poison Apple team of Court, Zack and Zoya are split up. Court is recovering from an infected wound, Zack has been imprisoned after being identified with facial recognition brought to Venezuela by a rogue CIA employee. Zoya is sent undercover to Berlin where she is identified by Russians wha have a kill order on her. I’m sure you can guess that Matt Handley will not allow Court to completely recover before calling him into service to complete Zack’s mission which he does. He does and then without permission he too heads off for Berlin to make sure Zoya is safe. Of course she’s in trouble and Court makes a last minute rescue.
Pay attention because there is more than one group of bad guys out there and they each have their own agenda which seems to involve killing at least one of the team.
This book is so packed with globe trotting action. It surely is RELENTLESS !!!!
Jay Snyder’s narration is first class.
This book has my HIGHEST RECOMMENDATION.
If you found this review helpful please indicate so.
Thank You.

Damn!

Damn! I finished it and now I have to wait who-knows-how-long for Book 11..

While not my favorite in the Gray Man series, this is a solid action-packed adventure. Lots of intrigue, the usual suspects plus plenty of new antagonists, with a good setup for future installments. Some nice progression in our hero’s character without changing the overall tone.

Excellent narration. I’m not particularly conversant with Russian, European, or Middle Eastern accents but I can say that I didn’t find any of them grating. Snyder’s reading conveys appropriate tension without overshadowing the story itself.

Damn again. Wish it could go on and on. I guess I’ll just have to go back to Book 1 and listen to them all over again!

Superb espionage thriller!!

Author Mark Greaney continues to impress as likely the best espionage thriller author currently living. Rather than write a review of RELENTLESS I'll simply refer the reader to the outstanding February 17, 2021 review by Shelley. Shelley is far and away the best reviewer of the mystery/thriller genre here on Audible. I've never met or communicated with her but I have listened to many books she recommended in her reviews and have never been disappointed.

I'm back after 5 months of listening to no audio books and writing no reviews as I cared for my wife of 52 years. She died two weeks ago after a five month battle with a cancer that is 100% fatal. As I grieve for my wife and struggle to begin my life without her Audible books will be a part of it. Our family, as always, will be a much larger part. Meanwhile, I have an audiobook backlog of almost 100 titles.

a ton of names

There were so many characters It was hard to keep track. It got confusing because a lot of the names were Middle Eastern Or Russian And when listening to a book you don't have the benefit of going back easily defined what character is with what name

Absolutely love “The Gray Man” series.

I try and savor listening to my audible book but it is hard. With Jay Snyder as narrator, you can’t put the book down. He takes you along in vivid color with every word! He creates a movie in your head and you can’t stop listening until it’s finished. I am now left to wait for the next in the series. Jay makes the Gray Man come to life!

Thank you Mark Greaney for this excellent series and for continuing to select Jay Snyder as the narrator. An EXCELLENT combination!

15 hours for 15 minutes disappointing

I don’t understand why proven writers with established characters feel the need to vomit words and gush for endless hours on non action details. But here we are. Love the gray man can’t say the same fir this yawner

Restarted This WAY TOO MANY times

What has happened to the story line of one of my favorite characters. OMG. Way too complex of a story and character names confuses the story even more. Ugg. Painful trying to get on the write path and understand this story.

Peak Gray Man

Greaney returns to form after probably the worst book (One Minute Out) in a brilliant series with one of his best yet. Loved really everything about Relentless and am already eager to find out what happens to Hanley, Zoya, Zack and Court.

Good, solid, relentless and wonderfully shallow.

Mark Greany is the AC/DC of modern spy thriller mayhem.

There’s a formula, it works and is entertaining as hell. Like eating at Macdonald’s.

Why change it?

The narrator is a natural for this type of material and pulls off his job flawlessly.

Fantastic new chapter in the grayman series, twists and turns to keep you listening. I could not give it a higher recommendation. if you find this as your first encounter with Court Gentry can I suggest to go back and start at book one. you will love it I promise.

Good story let down by over complicated sub plots

It is a good story, and narrated very well. The only issue for me is the over complicated sub plots. Whilst they do unravel and come to a head eventually, they often confuse and instead of intrigue on a situation level, the sub plots become messy and not clear. The main plot is good, just let down by odd sub plot clarity. It’s nearly like Mark Greaney had too many ideas and wanted to shoe horn them all in.
Still well worth the listen.

Boring

I love the series but it seems to be getting a bit flat and predictable now. Red Metal was great so Mark still has IT. Maybe a Hightower spin off just to freshen things up. I hope the next one is better.

A cracking listen once again, I found the Gray Man a couple of years ago and listened to all of the books now and already can’t wait till the next one comes out. Jay Snyder is the voice of the Gray Man, please don’t change him

An outstanding work by Mark Greaney& The Gray Man

A real winner from beginning to end. A heart pounding story I could not stop listening too. Do not miss the intricate story they moves from realm to realm with excitement and danger in every paragraph. 10 Stars for story & performance.

High Energy

I really enjoyed this latest edition of the Grey man series. It's high octane stuff and I look forward to the next one. My only criticism is that our hero didn't respect social distancing when he was killing people and was not very empathetic to the Russian assassin who clearly had mental health and alcohol issues and instead threw him out of a window.

Spectacular audio listening. This audio is as great as reading. A fast paced action with quips of utter coolness. Beginning to the very last sentence. I admire this author and the ability to have such an awesome audible presentation to complement the exquisite coolness of the Gray man.
