Purchase options and add-ons

A stellar new science fiction adventure from the author who redefined space opera, set in his bestselling Revelation Space universe.
 


For thirty years a tiny band of humans has been sheltering in the caverns of an airless, crater-pocked world called Michaelmas. Beyond their solar system lie the ruins of human interstellar civilization, stalked by a ruthless, infinitely patient cybernetic entity determined to root out the last few bands of survivors. One man has guided the people of Michaelmas through the hardest of times, and given them hope against the wolves: Miguel de Ruyter.

 

When a lone human ship blunders into their system, and threatens to lead the wolves to Michaelmas, de Ruyter embarks on a desperate, near-suicide mission to prevent catastrophe. But an encounter with a refugee from the ship—the enigmatic woman who calls herself only Glass—leads to de Ruyter's world being turned upside down.

Editorial Reviews

Review

"This wonderfully complicated, fascinating space opera carries on the adventures of teen sisters Adrana and Arafura Ness, who find themselves over their heads in deep space intrigue... [A] marvelous mix of character study and space adventure."―Publishers Weekly (starred review) on Shadow Captain

"Shadow Captain does what a great sequel should do: it builds upon, rather than replicates, the earlier work while escalating the drama and upping the stakes. ... The worlds'-shattering conclusion has us very much looking forward to our next voyage with the Ness sisters."―
B&N Sci-Fi and Fantasy Blog on Shadow Captain

"The sequel to last year's space heist story,
Revenger, is an equally-gripping story about two sisters, Adrana and Fura Ness, on the hunt for the greatest treasure in the universe."―Kirkus on Shadow Captain

"A swashbuckling thriller--
Pirates of the Caribbean meets Firefly--that nevertheless combines the author's trademark hard SF with effective, coming-of-age characterization."
The Guardian on Revenger

"
Revenger is classic Reynolds-that is to say, top of the line science fiction, where characters are matched beautifully with ideas and have to find their place in a complex future. More!"―Greg Bear on Revenger

"Alastair Reynolds [is] one of the leading lights of the New Space Opera Movement . . . .
Revenger is tremendous fun." Locus

"Reynolds has sketched in a galaxy littered with the relics of former civilizations (human and alien), with plenty left to the reader's imagination, and room for a sequel."―
Library Journal on Revenger

"An expert mix of the fantastical and horrific."―
Publishers Weekly (starred review) on Revenger

"Reynolds' newest action-packed science fiction novel is a tale of sisterly devotion, heartbreaking loss, and brutal vengeance . . . Fans will enjoy the well-developed characters and detailed world building."―
Booklist on Revenger

"By far the most enjoyable book Reynolds has ever written."―
SFX on Revenger

Top reviews from the United States

  • Reviewed in the United States on December 15, 2021
    "Inhibitor Phase" is described as a “standalone” novel in the Revelation Space Universe (RSU); but is it really? No . . . and yes. Can you read it without reading the other novels and stories in the RSU? Yes . . . and no. As you can tell, this reviewer is conflicted, and mainly because I can’t review it properly without recapping the rest of the works in the RSU.

    In the 1990’s, Alastair Reynolds published a short story introducing us to the RSU titled “Dilation Sleep” published in Interzone, a British SF magazine. Most of us on the US side of the pond never heard of it until much later. It would be followed by other short stories set in the same universe, one stretching 40,000 years into the future. Many of these stories are published in the collection “Galactic North and Other Stories.”

    In 2000, Mr. Reynolds debut novel “Revelation Space,” the first in a trilogy, blew the doors off the Science Fiction world and introduced a whole new subgenre of SF that later came to be known as “SF Noir:” stories told in the shadows, deep and dark, twisty and demented, with characters pragmatic to the point of cold murder who are just trying to survive in a universe filled with Inhibitors, aka “wolves,” an alien technological creation primed to eliminate advanced star-faring civilizations . . . like humans. The race to avert extinction was on.

    Next was “Chasm City,” another standalone in the RSU. Then the rest of the trilogy “Redemption Ark” (my favorite), and “Absolution Gap.” Afterward, two other novels were released in the RSU, the Prefect Dreyfus Emergencies, a duology named “Aurora Rising” and “Elysium Fire.”

    Why mention all these? Because "Inhibitor Phase" is a direct sequel to "Absolution Gap" (and the trilogy as a whole), and skillfully includes pertinent details from all of them! The way Mr. Reynolds did this is genius, giving just enough to imbue the action in "Inhibitor Phase" with some context so you don’t HAVE to read the others, and including helpful endnotes to guide the reader through what they might have missed. However, if you don’t read the others, you are missing out on a whole lot of deliciousness and depth of meaning.

    All of his works are challenging and not for anyone with ADHD. They require patience, a willingness to read hard SF that won’t violate the known laws of physics, and frequent reference to a dictionary. But, they are all worth the ride!

    A ‘standalone” novel should have a beginning, a story line, and a conclusion. But Mr. Reynolds has a difficult time providing satisfying conclusions. It is apparent in all his works. There are three reasons why an author might do this: 1) to leave room for them to return to this universe, knowing they should never tie up all the loose ends; 2) to engage that holiest of grails for an author, the imagination of the reader to fill in the gaps; or 3) they just don’t know how to end a story satisfyingly. Given how skillful this author is in telling the tales, I am leaning hard into the first two reasons. "Inhibitor Phase" is no different.

    It follows Miguel de Ruyter as he is kidnapped to join an impossible mission to find an ultimate weapon that might defeat, or at least deter, the “wolves” and give humanity a fighting chance. Meanwhile, those same wolves are on their heals in a desperate scavenger hunt to find all the pieces necessary to build the device required, even if they aren’t sure it will even work. It will take this ruthless band into an anarchic chasm of brutal gangs where they face a horrific space BBQ. It will take them into the photosphere of a star. It will take them into the mind-bending oceans of an alien personality and memory soup. Then into the crushing gravity depths of an ice giant planet similar to Neptune. Will the weapon work? Is it even a weapon? Hmm . . . that ending. It is full of evocative and absolute craziness. The author toys with the first person point of view, which is fun. It is also full of hope, because these hard-boiled characters will never give up.

    PARENTS: there are about a half dozen f-bombs in 450 pages; a nude scene that is not described, nor sexual in nature; some sadistic violence (that BBQ); and the overall tone is horrifying and depressing. If your young one is mid-late teens they will likely be able to handle it. The trade off is in expanding their imaginations, vocabularies, and letting them know they should never, ever give up.

    "Inhibitor Phase" gets 5 stars because of what it is. Fantastic, dark, and mind blowing. There are issues, to be sure, but it is well worth it if you are so inclined. Oh, and go read the other massive tomes in this series, either before or after this one. You’ll be glad you did.

    Without giving away spoilers, my main gripe is that I felt like the story was going to go in the direction of fighting the inhibitors, and I don't feel like it gave me enough of that. It felt like the book was building up to a massive payoff by setting things in motion, getting the characters prepared, and then when it came time for the payoff, the book ended without giving it to me.

    I don't know if there is going to be a sequel or if this was intended as a one off but I felt disappointment with the abrupt ending.

    That aside, the book reminded me of why I like Reynolds writing, and it's made me go back and re-read Revelation Space and the other books in the series.

    If the book had the finale I thought it was going for, I would have 5 starred it.

  • Reviewed in the United States on February 9, 2022
    This was an interesting book, not a quick read by any stretch but still ultimately enjoyable, Reynolds has a very elegant style to his writing. The story opens with a tiny colony of humans hiding beneath the surface of a moon orbiting a dying star, hiding from a nanotech intelligence that has been seeking out and destroying technological civilizations for aeons. The hook comes in when a castaway arrives at their shores with a potential means for successfully fighting back against the nanotech wolves. It's a good story and it goes in a number of thematically different directions (there are parts of the story that could be considered horror, parts hostage-rescue thriller, parts military-espionarge, parts tribal sacrifice, parts high-tech sci-fi) and the ending has a some very strong notes of "2001 A Space Odyssey".

    I've read banks, hamilton, vinge, simmons, and a huge number of other fairly good sci-fi authors. Reynolds is the best hard sci-fi author there is. (100% subjective).

    Zero spoilers about this book:

    It's a story about going out and finding something. Reynolds has done this in other books many times, even in other RS books. It is being part of that journey that makes Reynolds such a good (imo, the best) author. I love Banks (rip). He wrote some of my favorite sci-books (consider phlebas), but I always had a problem with the rainbow-happy-happy vibes of his Culture universe. With Reynolds, there is a grit. A not-so-perfect, certain-parts-are-barely-functional aspect to his universe that just makes sense to me.

    While the book's intro states that it is meant to be a standalone novel, I think that Chasm City is the only one that's really standalone. I would very much recommend reading Revelation Space to get all of the nitty gritty details explained for the topics that are so briefly mentioned in Inhibitor Phase.

    That said, if you have read Revelation Space, I think it is a privilege to be able to have another story in that universe that is written at the level of the other novels in the series. A lot of times, series tend to meander into strange places and lose a lot of the core readers along the way (dune). Inhibitor Phase brings in elements from the other books, we get another look at some places we've seen in other books. We get the same granular explanation of far-future technology. (something I think is so often glossed over in many sci-fi books)

    And, we get development. It's not just a rehash. It's another story in the universe.

    My only "complaint" is that there is there is sudden deluge of information/background that happens around chapter 8-10 that may be disorienting for totally new readers. But, for fans, there are a lot of things that happen in those chapters that link to other books that make a lot of sense.

    It's hard to write about how good this book is without ruining any of the "omg" moments I had reading it.

    If you are new to Reynolds and maybe don't want to make the 8000+ page commitment of reading all of the RS books, I'd say try House of Suns (standalone single novel) or the Blue Remembered Earth (3 books) series. Totally different stories, but they really show how reynolds can give this insane situation, blindside it with a problem, and then unravel that story for us to follow in a way that is worth the time.

    Easy 5 stars.
