A “compelling” novel of humanity fighting back against telepathically linked killers in a postapocalyptic world ( Library Journal ).

A quarter of a millennium ago, before the nuclear apocalypse forced the inhabitants of earth to flee their home planet, few humans could have imagined the course their path would take. Now, the orbital colonies are the final sanctuary of humanity and life is more dangerous than ever before. The colonists fear the return of their dreaded enemies, the Paratwa—ferocious warriors who are genetically engineered to exist in two bodies which remain telepathically connected. The new generation of Paratwa is far deadlier than the old, forming a powerful caste of fighter known as the Ash Ock. A mysterious virus infecting the humans database signals the return of their most feared enemies…

About the author

Christopher Hinz

53 books75 followers
Christopher Hinz is an author of science fiction thrillers – novels, comic books, screenplays and more.

Born in 1951 in Reading, PA, USA, his early passion for all things SF led to the writing of his first “book” in elementary school. A four-page epic, it featured a giant monster brought back from Mars who escapes and climbs the tallest building in Chicago, only to be blasted from that perch with a nuclear cannon. The inevitable fallout, along with other youthful digressions, steered Hinz away from science fiction writing – and Chicago – for many years.

His first mature work,LIEGE-KILLER, was originally published in 1987 by St. Martin’s Press. ANACHRONISMS, ASH OCK and THE PARATWA soon followed. The latter two novels, together with LIEGE-KILLER, form “The Paratwa Saga.”

A subsequent foray into comic books led to a number of publications, including creator-owned GEMINI BLOOD (with artist Tommy Lee Edwards) and DEAD CORPS (with artist Steve Pugh) for DC Comics, and BLADE for Marvel Comics, also with Pugh. An evolution into screenwriting resulted in the sale of BINARY, a script based on LIEGE-KILLER.

In addition to other SF projects, he has worked a variety of Earth-based jobs, including picture framer, turret-lathe operator, TV technical director and newspaper staff writer. He has played in rock bands, modeled dioramas and designed and marketed an auto racing board game. He currently creates new stories from the semi-seclusion of a wooded realm in Berks County, Pennsylvania.

5.0 stars (would give it more if I could). Book 2 of one of the best SF series that no one has heard of. Great world-building, great characters, fast-paced (never boring and no slow parts) and a terrific plot. Check out Book 1, Liege-Killer, and then read this one. You will not be disappointed. Highly Recommended!!

This is the second book in a trilogy, must be read in order. 56 years after the first book, the fleet is coming & it may well doom mankind to become slaves of their own creations. You'd think the entire race would do anything it could, but it's business as usual for all too many in the huge life cylinders orbiting the completely messed up Earth. Party politics, social climbing, & a lot of odd, seemingly disconnected events that hint only to the brightest & most paranoid that things aren't as they should be.

The world building is fantastic. Very believable & captivating right down to modern entertainments that could only take place in cans in orbit. The characters are memorable & the mysteries abound. I got so wrapped up in hurrying into the third & final book that I forgot to read this.

This has to be one of the best kept secrets of the 90s. I highly recommend it.

3.5/5 stars

I found myself a bit disappointed by Ash Ock after the fantastic and fun first book Liege-Killer. Ash Ock tells half a story that seems to be all set up with no real climax or resolution. There is a bit of retconning going on with Nick and Gillian because they seem to be very different characters from the first book. Nick’s suddenly a hacker and Gillian is now in a losing struggle with his monarch. I still liked it well enough, but I just wanted a complete story. The book has this entire subplot that is almost completely devoid of relation to the actual story and follows an inexplicably unlikable character. The storyline went nowhere and the final reveal did not explain much. This sequel lacked the sheer action and excitement I felt with the first book, and the plot seemed more confused and convoluted than complex and intricate. Maybe because I’m not seeing the full picture yet? I’ll hold off final judgment if this was worth reading after I finish the last book in the trilogy.

Hard to really review this one since it's not really one complete book, but half of the final book.

3.75 My Oldest Brother wrote this hilarious story about being at an airport and enjoying reading one of his favorite books but feeling like he needed to have a different book in front of it so people didn’t judge this one by its cover. 😅
Cover art man. It’s a killer sometimes

This trilogy is great. This is the middle book and it was really good. Great world building, great characters. Super fun read.

Book 2 of the Paratwa saga picks up 56 years later with the approach of the Paratwa fleet and deals with the intrigues and violence taking hold in the human colonies because of this. In the book the author does a good job pushing the plot forward and spinning out plot threads and keeping you guessing on the potential outcome he is heading for. He does not make the new characters he introduces as compelling as the main characters in book one were and the Paratwa bad guys are not the big unknowns anymore so they are anti climatic in a way. I still am interested in Gillan and Nick though so those characters keep me interested along with the story line and where it is headed. I would say this is a 3.5 star book but it does it's job and gets me to book 3.

[This is an old review I'm just now adding to Goodreads.]

Liege-Killer was a thrill ride, and I was expecting more of the same from Ash Ock. For the most part, Ash Ock took place 56 years after Liege-Killer, during the time when the Paratwa were scheduled to return to Earth and try to force humanity into slavery. It should have been an exciting book, as good or better than the first. Unfortunately, it wasn't.

As I fought to stay interested in the story, I tried to pinpoint the problem. Was it the characters? Jerem Marth was back, upgraded from whiny 12-year old to elderly Lion of Alexander. His emotional attachment to Gillian hadn't diminished over the years – in fact, it appeared to have grown. It was cringe-worthy, made more so by indications here and there that Gillian did not share his depth of feeling. Even so, Jerem was more bearable in this book than he was in the first. Susan, the series' new female POV character, was actually harder to deal with.

In this book, a couple men who appeared to be radical members of a group known as the Order of the Birch were unpredictably massacring people. Susan had the bad luck to be caught in the middle of one of their bloodbaths. Because one of the killers recognized her and feared being identified by her, she continued to be targeted and was soon on the run. Instead of focusing entirely on the problem of survival, she stressed herself to pieces trying to figure out how to both stay safe and keep a scheduled date. In her mind, avoiding breaking a date and thereby protecting her social status was at least as important as staying alive. I was dumbfounded.

I was relieved to learn that I wasn't the only one. Her own aunt didn't believe she was really in danger, because what person in their right mind would give equal weight to both safety and social status? By that time, I had begun to feel a little more sympathy for Susan, because I'd learned more about her history. Her parents had been members of the Reformed Church of the Trust. When Susan was 11, they killed themselves in order to ensure that they could receive an Earth burial before greater restrictions were put in place. Susan spent years in therapy, and I'm assuming that the iron grip she kept on her social status was a kind of coping mechanism. Even so: life > social status. I wanted her to realize that. I can't reveal how things went for her without majorly spoiling things, so I'll just say that I wouldn't have guessed from her earlier POV sections that her story would go in that direction.

Book 2's "prominent female character" count was higher than Book 1's, but I'm not entirely sure how I feel about them. There was Colette, quietly using need and desire in order to maneuver humanity into place for the imminent hordes of Paratwa. Even though her primary offensive weapon was clearly flawed, she soldiered on. On humanity's side were Buff and Martha, tough, confident female Costeaus. I ended up nicknaming them Gillian's “Bond girls,” because of the way they interacted with him. They were fighters, yes, especially Martha, but something about them didn't work for me.

I didn't realize it until I got to the end of the book, but the biggest reason why Book 2 didn't work as well for me as Book 1 was probably because Book 2 was primarily setup. Colette and Ghandi's sections gradually revealed the methods the Paratwa planned to use to enslave humanity. Susan's section's hinted at how humanity might manage to stay free. Book 2 only revealed and arranged those threads – it didn't tie them up.

Nick and Gillian's sections attempted to drum up some of the thrill and mystery that made Liege-Killer so exciting, but they failed. Gillian was too scattered, and his opponent felt far too flawed compared to Reemul. Nick's efforts to deal with the sunsetter program decimating E-Tech's archives only managed to be exciting for a couple pages.

Although this book definitely wasn't as good as the first, the paths it pointed to were interesting enough that I still plan to finish up the trilogy. I'll cross my fingers and hope that all that setup was worth it and that The Paratwa contains some serious badassery.

This is a sequel to Liege-Killer set 56 years later when the Paratwa and their Ash Ock masters are expected to return to Earth and colonies. While Liege-Killer resolved a couple of its plot lines, this book introduces additional plot lines and does not resolve any of them. If you read Ash Ock, expect to read the 3rd installment, The Paratwa, to see how it all concludes (at least I hope it concludes in the 3rd book).

Perhaps because the Paratwa universe is no longer new to me, I noticed some of the flaws in Hinz's writing. I think his writing is a little pretentious. He uses adjectives that are not needed and he uses more advanced language when a common word would better convey the meaning. I find that using the wrong word and other writing flaws break the pace of a book causing me to focus on the writing rather than the story.

This book delves more into the motivations and inner struggles of characters, but Hinz does not handle this kind of material as well as he dealt with the action and investigation in Liege-Killer. Some problems are solved and insights obtained with too little effort. In other cases, information is not readily available. It appears much of the colonies are under video surveillance, but when a mass murderer acts in public several times, there is no video of the killings or of the escape.

If you like the universe and the plot of Liege-Killer, then Ash Ock is worth spending the few hours it takes to read it.

Hinz’s second book of the Paratwa Saga continues the exciting narrative of the first, adding even more layers of intrigue as future threatening events are now imminent. Hinz writes in a very enjoyable style, mixing the mental drama of an unauthorised search/investigation with the visceral thrill of mass killings within a high-tech world – add the fearsome capabilities of the Paratwa and you get a fast-paced action story with all the filmic qualities of a blockbuster movie. I’m looking forward to reading the remastered conclusion of this great trilogy.

Ash Ock was a great book. It took a little time to get into it because so many years get skipped over between Liege-killer and Ash Ock. There are many new characters and some misdirection that really confuses what you think you know about the colonies and the paratwa. Having noted that I can safely say the book has great action, world building, intensity, and suspense. There are some returning characters despite the time lapse. The new ones grow on you.

As good as the first book in the series. The intrigues are layered and it's very hard to guess how the story will develop and yet it doesn't feel complicated. Again, how could I have missed the series?

A great second book, picking up some 56 years after the first. Diving straight back into the action and intrigue from the first book. I really love the world hinz has created, the paratwa are endlessly fascinating to me. Great fun.

56 anni dopo gli eventi del primo romanzo di questa trilogia i Paratwa stanno arrivando... Romanzo di "preparazione" alla conclusione della Saga dei Paratwa. Incalzante.

another amazing creation from Christopher Hinz. I don't know anything about this author but I'm hoping he's like, 12, so we have many many more years of his labor to devour as fast as he can write it.

Ash Ock
By Christopher Hinz
Publisher: Tor
Published In: New York, NY
Date: 1989
Pgs: 341

Summary:
Earth is an irradiated light that shines in the sky. The Earthlings live in metal and glass cylinders orbiting the planet. After hundreds of years, the Earth is healing...slowly. She survived the hammer blows of biological contamination, radiation, and the wastefulness of Man. Man escaped to the cylinders with his genetic descendents on his heels. The Paratwa, believed destroyed many years ago, are returning. They escaped the apocalypse as well. The twin psycho killing genetic creatures in humanoid form are coming home. Man isn’t inclined to welcome them back. The Paratwa are coming.

Genre:
science fiction, genetics,

Main Character:
Gillian, the surviving tway of the Ash Ock paratwa, Empedocles, the soldier of the Royal Caste. The traitor. The hunter of other paratwa down history, spending time between outbreaks in a cryogenic hybernation matrix. The one who shouldn’t have survived his tway being killed. The one who may be losing his mind as he can hear Empedocles in his mind...and sometimes, he can see Catherine, his opposite tway who was killed during the Apocalypse. Empedocles wants to bring on the interlace and hold Gillian in his sway for the rest of their lives never letting him escape the whelm...if Empedocles is real, that is.

Favorite Character:
Nick...cause he’s just such a manipulative bastard.

Least Favorite Character:
Susan Quint. She’s very much a social climber and not much else early in the book. Now there are layers added to her personality later in the book, but by then, the impression is made.

Favorite Scene:
Probably the Honshu Massacre. I can see that attack on that transport terminal in my mind’s eye. It’s big science fiction and action movie awesome.

Plot Holes/Out of Character:
The ghost of Edward Huromonus. The character is mentioned a number of times, but never actually appears in the story.

Last Page Sound:
Not as good as the first book, Liege Killer, but still pretty damned good.

Author Assessment:
I would read something else by this author.

Disposition of Book:
Keep it. Re-read it.

by Christopher Hinz, published in 1989.

The deadly paratwa - feared throughout the orbital colonies and heading back to the colonies from deep space to an inevitable invasion. What could be worse than a matched tway of killing machines? How about a matched threesome - and not the good kind!

Ash Ock is the second of the Paratwa trilogy by Christopher Hinz, and I can’t say I enjoyed it as much as the first in the series “Liege-Killer” because it was almost more of the same with less action.

That is not to say the book sucked, but rather it was repetitive with what already went on in the first. Oh the time has shifted fifty six years in the future, but the threat remains the same and Nick and Gillian are re-awakened to deal with it. It seems the hidden Paratwa in the colonies are preparing for their brethren’s return.

There are quite a few revelations in Ash Ock ( the Ash Ock are the ruling 5 of the Paratwa - like super-paratwa) and Gillian happens to be one of them even though his tway Catherine died long ago - which should have driven him nuts but didn’t - very strange.

Anyway, I don’t want to give too much away, but will say the Ash Ock and Paratwa are coming back from the stars where they fled to after the war that scorched the Earth, and they are coming back to rule over all. But the survivors of Earth and the colonies are not idly sitting back waiting for it to happen - they are planning a little surprise fo their own.

And since Ash Ock is the second of a trilogy you don’t get resolution of much and this volume pretty much ends right in the middle of the story so you have to pick up the last volume called “The Paratwa” to find out the ultimate ending to the story.

I’m going to finish off this trilogy for sure, but if you happen to read “Liege-Killer” only, I would say you have likely read enough.

It is rare to find a book that can rival its predecessor, but Ash Ock by Christopher Hinz is one that can do so. People battle their pasts with the knowledge that history repeats itself, yet there isn't anything to do about it.

Ash Ock is a sequel to the great Sci-Fy book, Liege Killer. With the odds stacked against them the characters must learn to clash with the escalating problem ahead of them. Hinz creates a stunning novel that leaves readers hungering for more. Ash Ock leaves readers ready for the end, the final story in his trilogy. I have to say I am one of those readers, ready for the next novel.

Succede pochino in questo Generazione Paratwa. Hinz accumula, accumula, accumula e alla fine lascia tutto in sospeso. Da una parte capisco che, trattandosi del volume centrale di una trilogia, si voglia arrivare col botto all'ultimo capitolo, dall’altra far arrivare il lettore annoiato e svogliato al gran finale non mi sembra una grande idea.

This book takes place 57 years after the first in trilogy, just when the Paratwa starships are set to return to Earth. Lots of new characters populate the pages, and like the first, this reads like a mystery thriller. I enjoyed this, but it really is only a segue to the final book; no abrupt cliff hangers, it just kinda stopped mid stride. 3.5 stars rounded up to 4.

This is just an interlude in the story, nothing is really resolved. The second and third books should've been a single book, just cut the repeated exposition from the third and it's all good.
