I don't think I've read a more exciting sci-fi novel since Neal Asher's "Owner" trilogy. This is sci-fi thriller writing at its best, I literally couldn't put the book down. How best to describe it? John Wick in space. Jason Bourne on an alt-Earth. Yeah, those work. All I could do while reading this was picture the John Woo version starring young Chow Yun Fat (Hard Boiled is my favorite action movie, soooo, yes I have good taste :D). If that could happen, please Hollywood, make it so!

I'm leaving a no-rating review here as a convenient way to post news about this book. Please "like" or mark this helpful so it stays at the top.

Cheers! I hope you all enjoy Zero World. I'm very proud of it!

I don't understand why so few people I know have read this, because it's incredibly fun.

If you liked Rachel Bach's Paradox scifi series or the Jason Bourne films (plus diverse MCs! Star Trek-y dilemmas! Spaaace.), this book is gonna rock your world. Also an easy transition for YA readers if you want to venture into adult SF.

Review to come.

Solid SF action/thriller with terrific world building. Way, way bigger and more ambitious than I was thinking based on the cover. The universe he's set up here needs more books, hopefully we'll get some. ...more

How do I know when a book has got its hooks in me? I read the digital ARC of Zero World from NetGalley which actually ends at 78% with the rest of it being bonus material. Of course, I had no idea of this going in and didn’t find out until I hit the Acknowledgements page. Having expected this unbelievably gripping story to go on for about a hundred more pages – then having that expectation cruelly ripped away from me – m

This one was actually pretty entertaining. At first. Spoiler warning: It didn't last.

Also, that ending? Seriously? I mean, SERIOUSLY? Who the bloody stinking shrimp stops a standalone book mid-scene, anyway? Without offering any sort of plot resolution whatsoever? I mean, what the actual fish?! Sorry, what? I sound a little bit pissed off, you say? Absolutely not. I am peace, calm and happiness personified at the moment.

See what I mean?

Review to come. Or not.

WOW WOW WOW WOW WOW!!!! Oh what fun!!!!! This book is the reason I love Sci-Fi! I can't believe it is not more popular! It was AMAZEBALLS! I only found out about Zero World through GoodReads Sci-Fi recommendations, and I am so glad I bought it! I listened to the audio version on Audible and it was FABULOUS! - One of the best I have ever listened to!

A sci-fi spy thriller with the feel of an action movie.

'Zero World' starts off strong, introducing us to Peter Caswell, a spy and assassin. To do his job, he relies on an implant which allows his handler to 'erase' all the memories of his missions, assuring that guilt and doubt never catch up with him. He approaches each assignment as a freshly trained, gung-ho agent, confident that he'll never have to ask questions or face the moral consequences of his actions. All he knows is that so far, he's

This book leans more towards thriller (with world building fantasy thrown in) than towards scifi. Peter Caswell is an assassin, and the gimmick is that his memory is conveniently erased after each mission so that he suffers no guilt about all of the people he has killed. His current mission is to find and kill Alice Vale, a scientist who went missing from a spaceship 12 years ago.

Peter accurately describes himself as a blunt instrument. Violence is his solution to every problem. The body count

“This will be the most interesting mission you’ll ever forget.”
Peter Caswell can’t remember where he’s been or what he’s been doing, but in his business, that’s par for the course. Caswell’s discretion isn’t just a professional promise; with the help of the implant at the back of his brainstem, it’s physically guaranteed. With his exploits wiped from his mind, Caswell is freed from the memory--and the responsibility--of every kill.

But when his newest mission sends him off to a mysterious spacesh

Well, color me disappointed. I was so psyched for this book. I'd heard it was John Wick in space - and I love me some John Wick ("I once saw him kill three men in a bar...with a pencil") - so it was a given that I'd read this. Now I wish I'd looked for this in the library instead of spending money on buying it. It felt flat story-wise and the characters weren't very engaging at all.

I received a copy of this title via NetGalley in return for an honest review, and honestly?


There are so many things right about Zero World, I don't really know where to begin.

The genre mashup? Yeah, that's a good place. The cover suggests a James Bond / Jason Bourne protagonist, and the back cover blurb tells you it's science fiction. Both very representative of what you'll find in the pages. But I think this book would appeal to readers of steampunk, as well. So if I were assigned the
Read the blurb. Sounds exciting, right? This superspy must be the most boring, blank-slate, spy ever in the history of fiction. He's got almost no personality, we're given nothing of his background, know very little about his current life, and what we do know is all suspect.

This book is like watching a football game if you know nothing at all about football, and have no reason at all to care which side wins. Sure, there's action, but no excitement.

This book has a 4 star average among my Goodread

So, take a spy thriller with an assassin who can't remember his kills and throw him into an alternate universe but make sure he, at some point, forgets everything of import that's happened to him. Thus is the boiled down description to the best of my ability for Jason M. Hough's Zero World. It's a book with a lot of ideas, a lot of action, not a whole lot of character development, an alternate world build, and a somewhat interesting lack of clear focus at the times when it most needs it.

Zero World by Jason Hough is an action science fiction rocket blast of a thriller and adventure...

“This will be the most interesting mission you’ll ever forget.”

Peter Caswell is a spy, a killer, and a professional assassin. He is also a man without a conscience. Caswell is able to be an incredibly ruthless and successful killer thanks to his special abilities which stem from a very ingenious futuristic implant. He is simply a man that is incapable of feeling guilty. Peter is a fantasti

Mediocre novel. Actually, would be more charitable to say the novel was too ambitious and failed. The idea was to combine a spy thriller with a massive SF world and the combination just doesn’t work. The book’s tone is off from the beginning. It’s long and slow. There are short action sequences followed by pages and pages of world description and characters trying to figure things out. It’s just too slow. It doesn’t help that the writing is somewhat flat and dry, without the tension of a spy nov ...more

Let me get this right out of the way. Zero World is fantastic. I couldn't put it down. I was lucky enough to get an advance copy and holy crap does this book deliver the goods. The world building here is masterfully done and the characters are richly imagined. I don't want to really say anything else about this book because I don't want to spoil anything. That being said, Zero World is downright kick ass science fiction. It transcends the genre and if you're like me and you loved The Darwin Elev ...more
Let the countdown to action begin as Jason M. Hough firmly etches his name on the A list of science fiction writers as he leaves you caught in the magnetic gravity of every single page. Welcome to Zero World where someone is playing Russian Roulette with the planets.

I enjoyed this but life got in the way meaning I was very slow to get through it which impacted my overall enjoyment.

The story is clever and an interesting premise and written stylishly but when you can only read a couple of pages a night before falling asleep then things just feel stilted. In no way was this the books fault but my own. I wish I'd approached this at a different time as I think I could have really enjoyed this, instead I just thought it was ok and was looking to get into my
Zero World is a fast furious powder keg of a novel. An ingenious plot makes the story all the more exciting. Jason Hough's fourth novel, following the winning and immensely readable Dire Earth trilogy of last summer, is a great summer read. The story is fresh, fast, interesting and intense and has great science fiction antecedents. Mixing elements of science fiction, Jason Bourne, Total Recall, assassins and Star Trek's Prime Directive, the novel succeeds on most levels.

Stunning and Brilliant! Zero World is an a high velocity science fiction mystery that will take your breath away.

Once again Jason M. Hough, the author of Dire Earth Cycle series, delivers with an amazing new adventure called Zero World.

Captivated from the beginning, this is sure to become an all time favorite for me and any scifi fan. The story is presented in a graphically violent and highly descriptive manner so it may not be a tale for the young reader. For me, that was enhanced by the amazi

Just as a bit of information you might want to know, the description of this book shows 592 pages. Well, that's not quite correct. Zero World is 445 pages long and the novella The Dire Earth takes up the remaining pages. If you read Jason Hough's previous series beginning with The Darwin Elevator (Dire Earth Cycle), The Dire Earth is set years before the events in Elevator. I read The Darwin Elevator when it was released and quite liked it so I was interested to see how the author would handle t ...more

Zero World is a fast paced tension filled science fiction adventure. It starts out as one thing then changes direction again and again. Peter Carswell is not that nice a hero and at first I really disliked him. He never get less violet but he did grow on me as the book progressed. He and Melni Tavan make a good pair. There is very good world building - much of it full of surprises. The back story is interesting and critical to the story line. Peter and Melni have to carry the story and they do a ...more

An exciting ride through a parallel Earth, with a (likeable) Jason Bourne-type in Peter Caswell and a kick-ass female lead in Melni. The alternate-Earth narrative is not something I'm usually into, but I liked this quite a bit. There are both similarities and startling differences between our world and the alternate Earth, and Hough does a commendable job keeping their two distinct speech patterns consistent, often on the same page. Action-packed and a surprising feat of world-building. ...more

While the largest bulk of my reading is in the fantasy genre, sci-fi is certainly the second largest part of my list. When I read sci-fi, I generally feel that I am not quite smart/nerdy enough to really enjoy ‘hard’ content, with focus on spaceships and math and realism and such – I often say I err towards the people-centric, ‘soft’ stuff, ala Scalzi. Beginning with his Dire Earth series, I certainly found that Jason Hough’s works fit enough in
