When a mysterious ultrasonic weapon attack may be the preamble to something greater, Agent Zero sets off on a global manhunt to stop the ultimate devastation before it is too late.

Agent Zero, trying to come up for air on the heels of the President’s impeachment and Sarah’s close brush with danger, wants to retire from the service and try to get his family back together. But fate has other choices for him. With the safety of the world at stake, Zero knows he must follow the call to duty.

Yet his memories are shifting, and with it, new secrets are flooding back. Tormented, at his low point, Agent Zero may be able to save the world—but he may not be able to escape from himself.

“Assassin Zero: An Agent Zero Spy Thriller, Book 7” by Jack Mars, narrated by Brian Callanan, is a gripping addition to the espionage genre that plunges listeners into a world of intrigue, danger, and relentless action. The audiobook is a testament to Mars' skill in crafting a story that is both expansive in its global stakes and intimate in its exploration of the protagonist's psyche.

The narrative follows Agent Zero, a seasoned spy grappling with the aftermath of political turmoil and personal loss. As he contemplates retirement and reuniting with his family, a new threat emerges in the form of a mysterious ultrasonic weapon attack. This sets the stage for a global manhunt, with Zero at the helm, racing against time to prevent an impending catastrophe.

Mars' writing is sharp and efficient, propelling the story forward with a sense of urgency that mirrors the high stakes of the plot. The author delves into Zero's internal conflicts, providing a nuanced portrayal of a man torn between duty and desire for a normal life. This internal struggle adds depth to the character, making him more than just a skilled operative; he is a man battling his demons, both past and present.

Brian Callanan's narration brings this internal conflict to life with a performance that captures the weariness and determination of Agent Zero. His voice conveys the gravity of the situation, as well as the personal toll it takes on the protagonist. Callanan's pacing and intonation keep the listener engaged, ensuring that the story's momentum never wanes.

The audiobook's production quality is commendable, with clear audio and consistent levels that allow for an immersive listening experience. The sound design is subtle yet effective, enhancing the narrative without overshadowing the story itself.

One of the standout aspects of “Assassin Zero” is its balance between action and introspection. While the book delivers on the promise of thrilling espionage action, it also offers a thoughtful examination of the protagonist's mental state. The story spends significant time exploring Zero's shifting memories and the secrets that come flooding back, adding a psychological dimension to the spy thriller formula.

In conclusion, “Assassin Zero” is a robust addition to the Agent Zero series that will satisfy fans of the genre and newcomers alike. Jack Mars has crafted a tale that is both action-packed and thought-provoking, while Brian Callanan's narration elevates the story with a performance that is both powerful and poignant. This audiobook provided hours of engaging entertainment.

Into the breach again, will this be the last time.

I love to read about Agent Zero. He is always in action and sometimes in the Nick of time. All the characters have become old friends and seem like family. Jack Mars is an excellent author for action, intrigue and adventure. He keeps you on edge of you seat and you can't wait to turn the next page to see what happens next. A great read for action and thrilling drama.

This was like simultaneously reading and watching a Hollywood blockbuster. You felt for Maya and the darkness she has discovered within herself, Sara dealing with drug issues, Zero/Reid unsure if new memories of himself as a dark agent outside the VIA are true and why are memories of Kate's name of Sara's face of how to load gun disappearing. In the meantime, bad actors are using an ultrasonic device as a weapon in highly randomized locales. What is the endgame and will they save the day

As much as I enjoy Agent Zero and his, almost, superhuman prowess! This book was disappointing on three main levels. Number one; he hardly gave any attention to their usual “death-.to-thousands-save-the-day-task! Instead he maintained an almost continual inner dialogue about what he thought he did, or did not, do in his past. Number two; We are talking about a man who has taken on multiple bad guys….at once mind you, and yet in this book he gets his butt kicked (literally) by a twelve year old! Lastly (spoiler alert!), when he is told his brain is going to be killing him and his memory loss of events, people, important things (like …loading a gun), is going to be permanent, what does he do??? After all the monologue about, “no more secrets”??? Yes, he’s not going to tell anyone! Hope he doesn’t end up trying to save one of his friends or family and forgets how to fight! Imagine a fellow agent going into a hostile situation and not being aware your partner might forget something at the most critical moment! Mind-boggling selfishness! The most disappointing in an otherwise excellent series so far.

Hmm. So I think the premise of the books are getting flimsier just as the attention seems to be gradually shifting to Zero and his personal life. I think this is one of the first books in the series where zero appears so unsure of himself during an op, and less vocal and vociferous than he used to be. If the subsequent books move to his own problems with his memory loss and all that...it might become interesting as most of the later books are a rehash of all that we already know.. about him and his tactics in the field. If you read them in quick succession they are pretty run on books and it's difficult to now distinguish one from the other. The sub plot with Sara was a tad bit too obvious and probably it would have made more sense if she hadn't given in to her temptation. I'd still read it because it is Zero but it's probably more because I have the books - I doubt the magic of the first three books can be recreated.

Worth 10 stars.

Another brilliant chapter in the life of Agent Zero. We continue to be there with him while he sorts his relationship out with his daughters and Maria. Then he gets a call taking him away from Thanksgiving with them to battle a threat from a new form of weapon.
Zero is also having memory problems which could have an effect on his actions as an agent. Definitely worth reading to find out how this all pans out. Superb as was the rest of the series.

Get ready for Agent Zero to kick some major a$$ in this action novel. As someone who has never read the Agent Zero series before, I was pleased by its speed and unique plot amongst a pretty used up genre. Mars does a good job of rattling us up with a variety of twists and turns. The secondary plot wasn't that interesting to me, but maybe if someone was reading these in order or had read a few before it would be.

The action was good and the balance between problems at home and problems in the world worked well. I also like the personal challenges that were introduced in the story which seem like they will carry on to the next tale. The only main flaw to me was that the motivation of the antagonist left me wanting more back story to her character.

Great Series

This series has been the first for me of reading Jack Mars books. I have found them to be consistently at a 4.5 rating. It is a very action packed series. This particular book was still good but the issue with his girls was a little bit draggy. I know they had been through a lot but their attitude towards their father made me wish someone would kick them in the ass.

Ok after seven books I'm done

The review is not just on this book but the series. I can't believe I read seven of the agent zero books before realizing they were just short stories following the same outline. The first 180 pages build a premise that ends abruptly in the last 20 pages or so. At the beginning I was hooked on what happens next, I'm over it.

This is the five-star rating system I use:

★★★★★ Great book! Can’t wait to read it again (and I will).
★★★★☆ Good book. I am glad I read this.
★★★☆☆ OK book. Nothing special but not bad.
★★☆☆☆ Not good. Why did I waste my time?
★☆☆☆☆ Lousy. I didn’t finish.

If for whatever reason, I go back and reread a good book, I will change the rating to five-star because I read it again.

Gotta zero in on Zero

The Agent Zero series has grabbed me and will not turn loose. Every time I get to the end of one novel I can't wait to move on to the next. I highly recommend this series. This series and Lincoln Rhyme are my two favorite series so far.

I kind of really like the characters in this series so will continue to read the books. As I am reading them one after the other I can't say in which book the mistakes are necessarily in but the author is beginning to take literary license. A judo kick doesn't exist. In Judy there is no kicking.

275 pages for 7$

It's a good book and great characters but come on 7$ for under 300 pages? For 7 bucks we deserve at least 400 pages.

Is he a CIA operative or an assassin? CIA operative Kent Steel, a.k.a. Agent Zero faces his past in real-time present -- and it is agonizing. Another Jack Mars page-turner.

Mars knows Jack!

Jack Mars’ writing is excellent and his research is even better. The spy fiction business is better for his contribution. A worthwhile read for any agency buff.

This one dragged for me. Character was too much in his own head. Too much family drama - theyre rather insufferable in this book.

These books are good quick easy reader. Nice thing to throw in the mix. Predictable- sure but sometimes you just need a book you don't have to think too hard while reading.

Good series, I'll finish it out with book 8. The relationship with his daughters was particularly good reading for me, as a father of 3 daughters.

My least favorite book in this series so far. Some fairly large assumptions had to be made about the lack of intelligence of the people in power for this to play out the way the author had it. While this is the case for many of the books in this genre, this one takes it past the boundary that even I, knowing the genre well, had a hard time with suspending belief in my mind.

Compelling read from the amazing Jack Mars. The story is full of heightened tension as the reader is swept into the lives of a flawed but brilliant special agent and his two teen daughters facing challenges beyond their abilities, but then, no. Their coping is pretty amazing.
It is hard to imagine more stressful situations, but that’s why we read! Escapist fiction at its best, but... I would sure like to edit this book. There are places where my grammar antennae go up!

I do love this series. Just when you feel like Agent Zero is going to get a break, the bottom falls out again. This time the plot did seem a bit contrived and it felt like the story was being pushed out there, and not really developing naturally. Other than that- there was enough good "feels" that have accumulated throughout the first six books that it made it easy to give it a bit of a free pass. There is still a progression of the story arc with Zero's life and we do get to a better place family wise so all in all - it's all good.

Just waiting to get book 8.....

Almost quit on it

It is standard Agent Zero, and in the beginning to formula like. But that changed as I read further. Excellent novel and I’ll read #8. However, please look for in March my son’s book, about Ben Porter, a FBI employee. You’ll love it and the sequel. It’s self published. Thanks.
