United States of Z - Book 1: A Post-Apocalyptic Thriller
Hiding in plain sight, Protocol 9 agents live among us.
Protocol 9 was designed as the ultimate safeguard—a top-secret government program to counteract viral outbreaks or chemical weapon attacks. But no one expected to use until something turned the population cannibal.
For Special Operations soldiers finishing their tours of duty, signing on as Protocol Agents seemed like easy money—a cushy contract with no real danger. But when civilization collapses and the streets run red, they realize they’ve been recruited as humanity’s last line of defense against a nightmare they never saw coming.
Protocol 9: When Survival Becomes the Mission.

January 14, 2026I'm not going to rate this one because I was pretty sure I wasn't going to be a fan to begin with. It's a tale of a military extraction of a doctor at the beginning of the zombie apocalypse absolutely not my jam (except for the zombie part).
I did like the zombies in this one and the way the infection operated, and I also liked how snappy things were. There were a couple of scenes that were really impressive too.
I didn't really connect with the characters and by now (a day after I finished reading the book) I only remember one of their names, Salazar and that's only because the author Jo Salazar wrote some of the best zombie novels I've ever read, there just wasn't enough about them for me to get invested. What we got was; they saw a lot of stuff in previous deployments, they're alone (no close relationships) but somehow not inhumane or plain bad people, and at least one of them is good at terrible inspirational stories, it felt very "yes and?" as far as character building goes. If you're down with beat by beat military style action your mileage will probably vary though.

Action packed
My first time with this author. This is about as action packed as a book can get. I don't want to write spoilers but are these zombies? A unique way to write an apocalypse story. Readers won't be disappointed. On to the next one.

The soldiers on the Potacal 9 team are going to need a miracle. The outbreak is worse than anyone imagined. Fast-paced military thriller.

This book was start to finish action. I would not consider this a horror book, more of a military/zombie book. I look forward to reading the rest of the books in the series.

United States of Z by Olin Lester is well worth reading. It kept me engaged from beginning to end.
The government created a secret group called Protocol 9. Comprised of former special operators who, during retirement, were specially trained and are on standby in the event of a biological attack on the country. It's easy money, as none of them ever expected such an attack. When it did occur, the teams reacted quickly.
Their first mission was to rescue a doctor who may have the cure against a biological weapon that has turned soldiers and citizens into zombies. Upon their arrival, the teams found the military base on the west coast overrun, and the zombie ranks increasing by the minute.
During the rescue, they are not only battling zombies, but it was discovered that Russian snipers are picking off Protocol 9 members during the chaos.
United States of Z is a fast-paced book and an excellent start to a new zombie apocalypse series. The characters are well defined and likeable, but how many of them will survive the mission? Highly recommended.

Not your average Z book
Let's start off with mentioning that this book doesn't faff about before things get going. Major pro. Written by an ex-military man, rest assured the terminology and the like are real.
Another pro here is these zombies aren't really zombies. More along the likes of hyper-aggressive humans with a desire for flesh. That retain some thought. It's creepy and new, to me anyway.
It's pretty fast paced, felt a bit short. A suggestion would be to lengthen the chapters and remove the full page chapter preface.
One of the cons is the VIP doctor that needs rescuing, I mean it's too perfect the way the outbreak just happens to start at the hospital that she just happens to be at. She's not a good character and not likeable at all.
A major con for me is the whole, "Russians bad". Really. That's been shoved down our throats for decades. Though, I suppose, no author would use the real bad guys of the world. I'll give book two a chance and decide if I continue or not.

I received this book as an ARC and I’m so glad I did!! This author is new to me. I read the prequel, then read this right after. The counteract the possibility of viral attack is a top secret government program to keep us safe. It doesn’t work as well as they had planned as the citizens become cannibalistic. The characters are so well developed. Humor,loyalty, stress and tears as losing some characters is heartbreaking. The plot is the doctor they need to help control the outbreak leads to the plot. I say grab this and enjoy!!

January 7, 2026So, this book suffers from the usual typos and things you see with self-publishing. I personally didn’t love some of the language used, like describing gunfire as “the sound of freedom” and such. Also, there’s a fair amount of referring to the future that really undercuts the stakes. For instance, while deployed in this zombie hot zone, the writer says of a character, “it wasn’t his first rodeo, and it wouldn’t be his last.” Ok, well I guess we know this guy survives. All told, it wasn’t bad, but it wasn’t good enough to me to continue the series.

WOW!
BEST zombie apocalypse book I’ve read yet… and I’ve read several after running out of zombie flicks to watch. Can’t wait to continue into Book 2 and the rest of the books in the series. HIGHLY recommend! Fast paced and very well written as to both the characters and all the action… I’m not military, but I understood everything author discussed with respect to the weapons, vehicles/choppers, etc., gear … even their lingo which he explained without detracting from the plot.

Needs proofread
The idea for the storyline was good but the wrongly used words, bad punctuation and bad spelling made reading it a bit of a headache. It really could do with being proofread! I certainly would have read the series if not for that but I don't think my brain could take another however number of books in that condition which is a pity because aside from that it was good.

Jingoistic, xenophobic nonsense, poorly written by an author that seems to have just discovered thesaurus dot com. "The evil of the man slipped from his body along with his soul" and "his sandals obtusely sailed through the air" didn't do it for me. Perhaps if I was really into reading about the minutiae of a military service members' every movement, along with jargon I didn't understand (and is never explained), this would have been my bag. But I'm not, and it wasn't.

Better than okay
This book has the same tropes as most books. Zombie outbreak, valiant military fighting impossible odds, a doctor that holds the cure. It also has some of the same failings, most notably paper thin character development.
But the book is well written and the pacing is excellent. It's a comfortable book to wind down the day.

Fun adventure dystopian thriller that leans into military action. There is a fare amount of military jargon but there is a helpful glossary at the end of the book. This was a solid introduction to the series. I plan on reading the next installment.

Good book, good story, but....
I find it hard to believe the author would use the word "medivac" instead of the proper word "medevac (medical evacuation)."

lot in a little
Only slightly believable zombie apocalypse but the narrative of how it begun was just weird it just jumps into who’s the bad guys with no depth to there reasons.

Rocky start
The writing focuses needlessly on details that aren't relevant. It changed the sex of one of the team 3 members from Chatty Cathy to just Mililken.

Great book
I love how they actually focus on the combat for once most zombie books either just don't get the combat right

United States of z. book 1
Very enjoyable read. Nonstop action up to the very end. More attention focused on the characters and less in the zombies. Can’t wait for Book 2.

Nice.
Loved the action, went from 0 to 60 instantly and didn’t let up the whole time. Can’t wait to read Book 2.

heart-pounding action
I like the relentless and heart-pounding action in this book, right from the beginning till the last page. The characters are good, sad that some of them die.
