American Operator: A Tier One Story (Tier One Thrillers Book 4) Kindle Edition
An explosive, high-stakes thriller of espionage and counterterrorism by the Wall Street Journal bestselling authors of Tier One.
A shocking attack in Ankara leaves the US Ambassador to Turkey dead and his chief of staff, Amanda Allen, in the hands of brutal terrorists. But Allen is no ordinary diplomat. She’s undercover CIA. The DNI and the President turn to Ember, America’s premier black-ops task force, and its deadliest weapon, former Tier One Navy SEAL John Dempsey, for help. To find Allen, Ember gets embedded in the most dangerous battlefield on Earth: Syria. But when all communications are disabled by an attack in Turkey, Dempsey finds himself with no backup—a lone shadow warrior racing against time to rescue Allen from her captors before she reaches her breaking point.
What Dempsey doesn’t realize is that Allen is just a pawn in a much larger game. A new player has already been unleashed: a legendary mercenary who matches the American Operator in skill, tactical prowess, and a killer instinct for survival. Now there is far more at stake than a kidnapped CIA agent. Dempsey and his team better get this one right, because the balance of power for the entire Middle East rests on their shoulders. And the new threat is far more dangerous than any Dempsey has encountered in his decades waging war against terrorism. Game on.

Review
"Best Military Thriller series on the market,"-Simon Gervais, best-selling author of Hunt Them Down
"As a veteran, thriller-writer, and fan of the genre, the Tier One series is as good as it gets. If you liked Tom Clancy's John Clark, and if you like Brad Thor's Scot Harvath, you'll devour the Tier One series." -Best-selling author of the War Planners, Navy veteran Andrew Watts
"Andrews & Wilson are masters of crafting tightly plotted, authentic action thrillers. The Tier One series packs a punch like few other thriller series can."-Best-selling author of the David Rivers series, Army veteran Jason Kasper
"If you look up the word thriller in the dictionary, you will find this series used as an example."-N.Gargano Amazon Vine Voice
"Powerful, compelling, raw gut-wrenching...One of the best espionage series I have ever read."-Frank Allen
"Wow! I can't put these books down! This series is some of the best story telling I've read in awhile. In this genre this ranks right up there with Vince Flynn, Brad Thor and Ben Coes with me!" -Steven Phillips
"A great book full of non stop action and one of the the most exciting books of the year." -Marie A.
From the Author
Thank you for following John Dempsey's journey as he evolves from a "door kicking" SEAL into America's most lethal protector.
In the first trilogy, we explored the Iranian threat as VEVAK spymaster Amir Modiri targeted America's elite Tier One unit, the office of the DNI, and risked World War III by attacking Israel.
With American Operator (Book 4) we kick off the second Tier One trilogy which focuses on the Russian threat to NATO, Eastern Europe, and the Baltics. In the Russian Trilogy, Dempsey faces his toughest adversary to date and must learn to adapt from a lifetime of Middle Eastern counter-terrorism operations to taking on an enemy fashioned in his own image.

- Reviewed in the United States on December 7, 2018This is book four in a series that promises to get longer, and that’s good.
I didn’t review the first three books, but in a nutshell: The main character, John Dempsey (formerly known as Jack Kemper), is an ex-SEAL who lost his entire team in an attack while deployed in the sandbox. In order to go after the people responsible for the attack, Kemper ‘dies’ and changes his identity to Dempsey, and becomes forever lost to his wife, his son, and all of the operators he has ever worked with. He becomes the founding member of an ultra secret, very small cell of highly skilled people who are known only to the president and one or two others. The group is called Ember and they are assigned missions against terrorists that cannot be performed by any other group. They operate autonomously, choosing targets whom they declare to be the greatest threats to America.
Throughout the first three books the team recruits members, loses members, and completes a variety of dangerous missions that are beyond the capabilities of other special forces groups. We watch as interpersonal relationships form, and we watch as various members mature and become even more skilled at their various callings. The growth of the team, both as individuals and as a cohesive, interdependent fighting unit, mirrors how such a group may evolve in real life, and it is gratifying to watch as the team expands and grows in capability.
Interestingly, the authors’ writing abilities seemed to grow along with the fictional team members. When starting the first book, I got the impression that it was written by amateurs. The writing was shaky and unsure at times, the actions of the characters seemed overwrought and unnatural, and it seemed as if the authors weren’t quite on the same page. (And if they had used the term “tier one” very many more times, I would have deleted the thing from my Kindle!) But by the end of the first book (called “Tier One”, naturally) they had their act together and the book turned out to be pretty good – enough to make me want to get the next one. Books two and three each improved on their predecessors, and by the end of book three I was disappointed when it looked as if there were to be no more books by these guys.
And then book four, “American Operator”, came along. This book is probably the best written of the batch so far. It doesn’t exactly pick up where the last book left off, because that story seemed finished. But it does continue with the same characters doing the same dangerous stuff. This book opens with the Ember team conducting a strike against a terrorist group. The bad guys are killed, the good guys are rescued, and all is well. During the mission, however, a person named Malik is revealed; this guy (or the idea of this guy…) is woven into the fabric of the rest of the story, and likely into book five.
Briefly: a young CIA agent is captured during a terrorist attack in Turkey. She is taken away, and Ember is tasked to find her. Dempsey is separated from his team as a result of a seemingly unrelated attack in the same country, and much of the book focuses on his efforts to rescue her. As the book progresses, the captured agent is confronted by Malik, and it is revealed that Malik is part of a plan that goes far, far beyond a simple kidnapping. By the end of the book, the agent is rescued, Dempsey confronts Malik, the president and associates get attacked, and the larger plan is revealed (to a degree). Ember gets new personnel, some soul searching is accomplished, somebody has an epiphany, and all is right again.
Except it isn’t. Unlike the first three books, each of which seemed to have a solid conclusion, this book is open ended. While the good guys make it back home, the events in which they participated are far from over. The ‘big plan’, perpetrated by the Russians, is still in play. The fallout from the attack on the president and its implications for Turkey and the United States are not discussed, leaving the door open for a follow-up. And a traitor is still undiscovered. All of these factors create great anticipation for the next book, which unfortunately is not due for a whole year (November 2019).
Naturally I have some rants, but they are few. While most of the book is written at a perfect pace that prevents boredom yet leaves room for character development and background information, the ending is a little bit “television”. The showdown between Dempsey and “Malik” lasts forever. Their battle goes way beyond what normal humans are capable of (think Jason Bourne on amphetamines) and their continued escapes wear a little on the otherwise credible action. And the “love-in” at the end is a little much. However, this is a good book, the best so far. I recommend you read them all, and most certainly read them in order. And maybe don’t start them until just before book five comes out so you don’t suffer any withdrawal symptoms.
- Reviewed in the United States on October 5, 2024I've read other of these Navy SEAL/ spy books and this series is by far and I
mean by far the very best. The plots are great, the writing is excellent, the characters are well fleshed out and there don't appear to be any obvious mistakes about details. About details and, in addition, these riders handle geopolitics with surprising accuracy.
- Reviewed in the United States on January 9, 2025The series continues to evolve and increase in complexity and intense action. Looking forward to the continued efforts of Team Ember to fight the good fight
- Reviewed in the United States on March 8, 2025One of my favorite book series
- Reviewed in the United States on January 8, 2025New revelations and evolving relationships rule the day in this series! Love it! Cannot wait for what the future holds for Ember and its members!
- Reviewed in the United States on March 11, 2024This book, as do all that the authors write, inject the contemporary political and strategic narratives of our time. The primary actors are well characterized and the bond of friendship is evidenced by the interaction of the members of this clandestine counterterrorism group. A well written, suspenseful, and excellent ting read.
- Reviewed in the United States on March 27, 2022This was a close-up look at a day in the life of a top secret group that fights terrorists. Similar to Delta Force, they travel the world fighting the bad guys for what is right. A Good read.
- Reviewed in the United States on May 28, 2024Love love LOVE...did I say LOVE..this series install book #4, American Operator. The build up of mystery and espionage on every page lead the readers to have shallow breaths in anticipation of the action and finale badassery to come.
In fact, the action scenes are so well written, that I envisioned the action as it played out in the story.
Awesome read!

5.0 out of 5 stars American Operator
All action hero Dempsey and Ember are at it again. Another cracking, faced paced and all action read. I’ve said this before, this series of books, Dempsey and the Ember team are easily on par with Lee Child’s Reacher series. In fact, Reacher is a loner, where these books have Dempsey and the team, which brings different aspects to the plots. This book could easily be read as a stand-alone, however my recommendation would be start at the first book and read your way through. Firstly, there are mentions within this book that you will fully understand from the previous ones and more importantly, your missing out if you haven’t read the earlier stories. It’s also good that things don’t always go right for Ember and that the bad guys live another day. These are a great read and I look forward to the next book and the following how the plot continues to unwind. A definite 5 out of 5 from me. Download the books and get reading!

5.0 out of 5 stars Former Tier One Navy Seal John Dempsey und die Ladybugs
Amanda Allen wurde in der Türkei entführt. John Dempsey und sein Ember Team sollen sie finden. Die Spur führt nach Syria. Während Dempsey als Teilnehmer einer UN Giftgas Inspektion in das Land einreist, gerät sein Team auf der Nato Base Incirlik ins Kreuzfeuer eines terroristischen Angriffs, der ihren Exfil Plan für Dempsey und Allen zerstört. Auf sich allein gestellt, macht sich der former Navy Seal auf den Weg, Amanda Allen aus den Händen ihrer Entführer zu befreien.
Die Story klingt einfach, ist sie aber nicht. Das Ember Team und allen voran John Dempsey werden erwachsen. Sie werden nicht nur mit den Entführern konfrontiert, sondern auch mit der ganz speziellen undurchsichtigen Lage in Syria. Kurden, die Krieg mit der Türkei führen. Türken, die Krieg mit den Kurden führen, die Daesh supporten und mit Russia liebäugeln. Die Russen als eigentliche Drahtzieher der False Flag Ops, die die Nato destabilisieren und die Türkei zum Austritt bewegen wollen. Ein amerikanischer Präsident, der das nicht durchschaut und in die ultimative Falle läuft und ein "man not Malik", der im Auftrag des FSB die wet Jobs erledigt, ein russischer, noch unentdeckter Mole neben Kelso Jarvis, dem DNI ...
Die Geschichte ist äußerst real und spannend in die heutige Geo-Politik eingebettet, authentisch und brutal und zielführend. Ein Operator ohne Overwatch ist ein toter Operator.
Das Ende ist offen, das Chaos perfekt und lässt den Leser, also mich, mit einigen losen Enden zurück, die mit Sicherheit im fünften Band fest verknotet werden. Ich freue mich riesig darauf.
Ein tolles Buch, eine tolle Geschichte und ein Dempsey in Höchstform. Wobei es Sinn macht, die Bücher chronologisch zu lesen. Es lohnt sich auf jeden Fall.

5.0 out of 5 stars Another smashing read from the Tier One series
Thrillers and military fiction is one of my favorite genres and comprises a lot of the reading that I do. This is one of the best current series in the genre. I give 5* grudgingly, and have given every single book in this series a 5. The plot is totally believe, the character development is simply outstanding and the action is breath taking. Another masterpiece by one of my favorite authors. Absolutely loved it.
