As a big fan of Ancillary Justice and its direct sequels, I was excited to read another book set in the same universe. I enjoyed references to the previously established worldbuilding.
As is often the case with companion series, I enjoyed returning back to the world but I didn't find the story as impactful or memorable as the original story. I didn't find these characters as compelling as the previous protagonist and the stakes just don't feel as high.
All that being said, I still enjoyed spending time with this installment and would recommend to other fans of Imperial Radch universe. Ann Leckie is an excellent writer with solid prose and a clear love of the genre.

Ann Leckie is SO back! This is by far my favorite extended Radch-verse novel outside of the main Ancillary ___ trilogy. 4.5
An ensemble cast gives you a look into a city in crisis at the fringes of the dissolving Radchaai empire. Seemingly small-scale household dramas, political machinations, religious disputes, and urban planning are somehow are somehow all woven together in a way that somehow make a compelling story. Although the decentralized plot and larger cast of characters took a while to get going, the second half of the book made me stay up until 12:30 am to finish.
So glad I got to read this ARC and definitely recommend to others once it’s published!

I’d never read Ann Leckie before and I’ve always wanted to. Radiant Star is a standalone set in the same universe as her Radch series. I enjoyed the read but I suspect I would have gotten more out of it if I’d read the series first.
I loved Radiant Star and kept finding myself reading late just to race through it! The bureaucracy of colonizing a conquered planet is a constant presence throughout the book. I know this sounds impossible but it wasn’t boring!!!! I found myself crazy invested in the systems of religion & local government. I wanted every detail about the water treatment plant, the food shipped in from off world and how the military was utilized to control the local population.
Leckie is clearly highly intelligent. There’s so much to think about it could take a masters thesis to pull it all apart. It felt like it was all background to the story. The details contributed directly to understanding our characters, none of it felt unnecessary. I wish I’d read it with a book club and could spend an hour talking through it!

This was fine. Radiant Star is fine. I want to start this way because I want to ground myself in the actual experience of this book and not succumb to temptation to laud it because of Ann Leckie’s name being attached to it. If you go into this expecting something with the same epic scope as the Imperial Radch trilogy or the deep exploration of alien identity of
Translation State
, I think you’ll be disappointed. But if you look at this as an interesting, intersecting set of stories that happen to take place on an alien world on the edges of the crumbling Radch, then you will probably enjoy it. I received an eARC from NetGalley and Orbit in return for a review.
The people of Ooioiaa worship at a place called the Temporal Location of the Radiant Star. When events elsewhere (you know the ones) cut the planet off from the rest of the Radch, the people in power jockey for position and for survival. Radiant Star follows several characters, including the Radchaai governor of the colony, a lowly consoror who was raised to be sent away by his consorority, and an ungrateful heir and his scheming wife, and a priest who might become a saint. As their stories intertwine and their goals flow together or against one another, the situation on Ooioiaa worsens, and the drama unfolds.
Leckie uses an omniscient narrator here, which is such an interesting choice. Limited third person is all the rage these days, and even when that limited perspective head-hops, it usually happens across chapter breaks or section breaks. This narrator is truly omniscient, albeit personified as an unnamed author (presumably Ooioiaan) writing about this time from an unspecified point in the future. Their tone is dry, sardonic, yet also a little scholarly. Nevertheless, they provide access to the thoughts and motives of almost every character we meet.
The challenge with an omniscient narrator is that it can make your characters feel flat. When every character is explained to us, when all their thoughts and feelings are lain bare, they become less interesting. There is a power to the mystery created by a more limited perspective. Radiant Star lacks a sense of true danger because we never get close enough to any of the characters. Some are more sympathetic than others, of course. But at the end of the day, the arm’s length nature of the narration means I definitely felt more like I was reading a historical treatise than an intense story following a few characters.
On the other hand, the omniscient narrator gives Leckie more licence when it comes to the scope of the story. I love how each of these standalone Radch novels introduces us to new and interesting cultures on the fringes of Radch society. The frequent shifts between personal pronouns for the same character, depending on which perspective we’re tracking, signals this overtly. As always, I love how Leckie plays with ideas of gender as social construct. But more importantly in Radiant Star is the idea of food as both status and cultural symbol.
Radiant Star is in many ways a novel about the fall of empire from the perspective of a farflung province. Instead of a dramatic rebellion, we see a quiet devolution of power. The supply lines dry up. Famine ensues, unrest, martial law. The governor ponders what to do. All the while, Ooioians who know and care nothing for the wider Radch ponder power and jockey for their own positions within this particular society, and it’s fascinating.
As always, Leckie is so skilled at creating a memorable society that feels both alien and human at the same time. This story does not have the same intense personal and political scope as the first trilogy, and I also didn’t enjoy it as much as some of the other standalones we’ve seen. But that isn’t to say you should sleep on this one if you’ve enjoyed the others.

I am delighted to read a standalone Radch book that I unequivocally enjoyed with no caveats! I loved the initial Radch trilogy, did not care for Provenance, and really enjoyed Translation State with a couple of sizeable "buts." Outside the Radch universe, I really enjoyed Raven Tower and Leckie's short fiction collection, Lake of Souls.
This book takes place during the events of the first trilogy but on a sunless ice planet far from the Radch civil war. Leckie does an excellent job of pacing the rising tension of the book--and there's a surprising amount, given that the book isn't particularly action-heavy. Themes of the relativity of cultural norms and practices will be familiar to anyone who has read Leckie before, but this book also does some nice deep dives into the personal, and how the shifting slipperiness of the stories we tell ourselves allows us to reckon (or avoid reckoning altogether) with things we have done.
Jonr and his charge were my favorite human characters in the book--I would be so happy to read more stories about them--and Justice of Albis was a total delight.
This book has politics without wandering into the weeds or getting mired in intrigue, characters it's easy to care about but that left me wanting to know more (in a good way), and high stakes for a planet without losing sight of the personal stories that made the outcomes matter. The macro and the micro were well-balanced and the pacing was excellent. Honestly, no notes.
This is a smaller, quieter story than the Radch trilogy*--the struggles and dramas are on a smaller scale--but it is very good and I'm so glad I got to read it. Netgalley and Orbit Books provided an ARC in exchange for an honest review, and I'm too fussy about books to give any other kind.
*It couldn't very well be otherwise, being so far from the center of the action... and honestly, not every story can have a supreme ruler of a systems-spanning empire going to war with iterations of themselves.

The latest book in the Imperial Radch series is an intriguing, thought provoking, and, at times, cheeky stand alone entry in this long standing series. This book is set just after the original trilogy (Ancillary Justice, Ancillary Sword & Ancillary Mercy) in the timeline, but focuses on the politics and religions of a small, isolated world that is almost entirely cut off from the rest of the Radch universe and, therefore, the plots of all the other books in this series. Despite this fact, however, this is a book best read after you’ve enjoyed the rest of the series.
As with all Ann Leckie novels, this book follows the stories of multiple characters through a series of politically heavy events. The characters grow throughout the tale and their stories eventually weave together through the narrative, even if some characters never meet. I find Ann Leckie’s books almost impossible to describe except to say that if you like your SciFi on the thinking side, you’re sure to enjoy her complex world building and examination of unique alien and planetary premises. No two books are alike and Ann Leckie is truly a master of creating alien beings and cultures that somehow are never alienating to the reader. These are the books to read when you want to see and feel the commonality and humanness even in the other. Radiant Star is no exception and any fan of Ann Leckie or thought provoking SciFi is sure to love both this series and this newest entry.
Thank you to NetGalley and Ann Leckie for an ARC of this book.

I did not realize this was part of a larger series. As a standalone yes, but I was so very lost. I think if I’d read the series this book is attached to, I would have been fine. This is a very certain type of sci fi. The beginning grabbed my attention, however after a 30-year time hop, it was deep into political drama and lots and lots of details. It’s incredibly written, don’t get me wrong, but I think this is “a right time and right place” kind of read. Neither of which I was in. I think I want to go read the foundational series and come back to this one.

Did Not Finish
March 24, 2026The writing style is impersonal. There's many characters, and I never felt close to any of them. The narration always keeps you at a maximum distance.
It always felt like this book was expecting me to laugh at the satire of bureaucracy before me, but I didn't find it funny. I found it boring.

Leckie knocked this one out of the park.
This is in her Imperial Radch universe, about a smallish but significant city/planet that becomes a Radch territory just as the Radch empire is falling apart from the events in the original Ancillary trilogy. This planet is home of the Temporal Location of the Radiant Star, a site of saints and pilgrims.
There are a couple of really interesting characters you follow in this story, and their paths wind together. Also the usual Leckie stuff with species having different genders and pronouns. Plus there is an unnamed narrator in the midst of this who is has an amusing viewpoint.
Perfect for fans of Leckie but it also might be a good entry point into her writing.

Мне нравится, как вбоквелы к Радчаайской трилогии исследуют другие уголки вселенной и другие культуры, но при этом не теряют связь с основной трилогией. Раскачивалась долговато, но концовка того стоит.

The moment I found out this book existed I pre-ordered it and, in the past weeks, basically vibrated with excitement to lay my eyes upon in. And, thankfully, Radiant Star was so worth the wait! Truly Ann Leckie at her best as she presents us a small, underground city facing occupation from a crumbling empire, food shortages, and a grand religious event that will be the last of its kind. Leckie has populated this city with a whole host of characters that we follow as they deal with these events and the impact they have on their lives.
I have always loved Leckie's ability to create cultures that are not monolith--her worlds are always populated by different ethnic and religious group that influence the position, worldview, and agency of her character. In Radiant Star, she shows off that ability in full force and I love how intricately crafted the city of Ooioiaa and its habitants were.
Out of all the Radch books that aren't the main trilogy, this one is definitely my favorite. I love how selfcontained it was, yet the events in Radiant Star still connect to events that happened in the other books.
I also really enjoyed the narration style. If Leckie can do anything it's pull off a non-conventional narration style, I know that's right!
All in all, tens across the board for me!! 🌌🦠🧅✴️

This is a sidebar story to the Imperial Radch universe, describing what happens on a backwater planet with dueling religions when the Radch Civil War breaks out and all contact is cut off. The Radch governor is a capable bureaucrat caught in an untenable situation with food shortages and feuding factions. There's quite a bit about 'God and mammon' as the religious leaders jockey for position and wealth.
Meanwhile, a boy who was bred for sale off-planet is trapped in suspended animation and finally let out after thirty years. He tries to come to grips with his new reality while caring for a damaged Radch citizen.
This has Leckie's trademark humor but also the horror of a repressive society that can destroy its citizens. It's an encapsulation of her thesis about autocratic empires, writ small on a single planet that nobody in the Radch empire really cares about.
It could be read as a stand-alone, but really you shouldn't start here. Start with Ancillary Justice.

I love that Leckie is coming back to the world of Imperial Radch but is willing to do one shots on the periphery. Also, ngl, I love that this novel's speaking voice is essentially similar to the narrators in a Victorian novel, except for a culture we don't know, and is willing to razz the reader a bit for not knowing "civilization". We get a fascinating comedy of manners that also overlaps with a pending Imperial annexation, and all the fascinating things that can happen when social rules are in flux, or the place where you live is in a liminal position of not knowing if it's going to be annexed or not. Incredible character and narrative voice work here, the plot's great, and I love that we get more ancillaries as characters while we're at it. Comes out in May, preorder it now.

As always, it is such a delight to get to read a novel from Ann Leckie. I adore the Imperial Radch world so much and every book in it is a must read.
This one’s builds so quietly and slowly, in such an obvious way that can’t be changed. It was so much fun to read. Jonr and Keemat were both such standout characters for me. I loved how their stories (and every character’s story) all connected at the end. The Justice of Albis was delightful, I love the ancillaries.
Fantastic read. It’s made me want to go back and reread all the books in this world.
Thank you Netgalley and the publishers for the ARC.

Review of advance copy received from Netgalley
Ann Leckie’s Imperial Radch series was one of the first major series in the contemporary “space opera about empire and gender” SF movement of the past decade, and while those books featured giant warships and lasers and Imperial politicking, it was clear that Leckie’s heart was more interested in the quieter moments, quirks of character and the cascade of small decisions. Since that initial trilogy, Leckie has returned to her galactic setting three times, each for standalone books focused primarily on other locations interacting with the Radch. Radiant Star is the third and latest of this endeavor, and it’s a bit of an odd one.
Radiant Star is entirely set on the planet Ooioiaa, an ossifying, isolated world whose inhabitants live beneath its frozen outer shell, ruled by three squabbling sects of a faith focused on the prophesied return of the eponymous Radiant Star, a star that supposed once warmed the planet but has since left on its interstellar journey. Near the beginning of the book, the planet is conquered by the Radch, who have little tolerance for their strange faith, chiefly targeting their tradition of turning a celebrated few into “living” saints, kept perpetually in a near-death catatonic state and sealed in a tomb to wake the return of the Star. A series of self-serving political machinations lead to a pillar of the community being selected to become a Saint - the last one tolerated by their new Radch overlords. This small concession sets into motion a chaotic series of power grabs, honest mistakes, and embarrassing overreaches that threatens to destroy Ooioiaa.
That summary might lead you to believe that this is a novel filled with dramatic betrayals, action setpieces, and melodramatic scheming, but Radiant Star doesn’t feel like that at all. The book features an anonymous narrator describing the events of this tense moment with something of a jovial, mid-century British comedic voice. It’s not like Fire and Blood, the in-universe historic text of the A Song of Ice and Fire/Game of Thrones world. But it does keep something of a remove from its characters, despite telling us their anxieties and plans.
The strongest part of the book is the carefully orchestrated series of events, each one stemming from some small decision or personal foible, each one fairly innocuous in the moment, but together, catastrophic. Leckie is fascinated with the ways societies and systems fail, the way each individual piece thinks they’re making rational, self-interested decisions while failing to see what fresh horrors await them.
But personally, there’s something lacking here. The Imperial Radch series’ contribution to the recent SF gender discussion was the empire’s lack of gender and universal use of she/her pronouns for everyone. In these subsequent standalone books, the narrative focus is on other planets and cultures, all of which have used some form of neopronouns. I’m supportive of this idea - more science fiction and fantasy should explore alternative genders and ways of being - but their use here feels perfunctory. Leckie rarely describes the physical appearances of her characters; perhaps this is to further alienate readers from assigning our gender roles to them, but combined with the liberal use of neopronouns without any meaningful cultural distinctions, they don’t signify anything at all. I’m a very visual reader, and need to have some image in my head to really connect with fiction. Without any physical or gendered markers at all to the characters, coupled with Leckie’s sparse and distant voice, it’s hard to connect emotionally with any of the characters, and with the story at large. Without going into spoilers, the way the story wraps up also feels quite anticlimactic, and left me wondering what was the point of the whole endeavor.
All that being said, Leckie is clearly one of the preeminent voices in contemporary SF right now, and the Rube Goldberg machinery of Radiant Star’s plot was always compelling, even if I was held at a remove.
Thanks to NetGalley for the advance copy in exchange for an honest review. All thoughts expressed are my own.

Without going into spoilers, the way the story wraps up also feels quite anticlimactic, and left me wondering what was the point of the whole endeavor.
All that being said, Leckie is clearly one of the preeminent voices in contemporary SF right now, and the Rube Goldberg machinery of Radiant Star’s plot was always compelling, even if I was held at a remove.
Thanks to NetGalley for the advance copy in exchange for an honest review. All thoughts expressed are my own.

**Review of advance copy received from NetGalley**
3.5 stars—maybe 3.75?
After thoroughly enjoying Provenance, unfortunately I found this standalone somewhat disappointing. As excited as I was for a new Radch Empire novel (post AI-Ancillary upheaval), Radiant Star, while technically proficient, feels a bit on the wry/dry side. Perhaps the author intended a departure to explore a different tone/style? Could be that Leckie’s choice of “third person narrator” to describe events and character motivations made it feel inaccessible, and furthermore, somewhat frustratingly, their identity is never revealed (Justice of Albis?) so there’s no context provided. Thus, the story seems more like a detailed recounting, its “characters” largely unrelatable. The liberal use of unfamiliar gender pronouns adds another layer of impenetrability, complicated further by the overlay of Radchaai language (which has no other pronoun than “she” to refer to others.)
Set on the insignificant planet of Ooioiaa off the interstellar path, events center on its fractious politico-religious hierarchy and grasping factions jockeying for power. In the midst of this, the Radchaai arrive and take control of the government. Perhaps intended to illustrate the inevitable repercussions of larger events (“described elsewhere if the reader is interested” as the narrator often coyly reminds us), in this respect, the novel works as intended. A fragile détente, simply awaiting the right conditions to unravel. Cut off completely from the outside world, the tenuous supports of society and economy quickly break down. (I also spent some time wondering whether I was supposed to remember Jonr’s consoror as a significant character from the other Radch novels.) The novel has its breakthrough moments, when characters act with altruism and emotion, but largely most are unable to think beyond themselves.
Ultimately, events come to an appropriate resolution, and despite drawbacks, the novel represents a significant expansion of Leckie’s post-Radch Empire world. I just found myself wishing for something more engaging.

This latest entry is probably the weakest of the six novels in author Ann Leckie's extended Imperial Radch saga so far, but it's still an enjoyable enough time that I'm comfortable giving it three-and-a-half stars (radiant or otherwise), rounded up. It takes place during / after the big civil war from the original trilogy, but you don't necessarily need to have read that first if you don't mind encountering a few minor spoilers for it. Likewise, although it would help to come into this book with the background understanding of how spaceships in this setting have artificial intelligences that they can distribute around to pilot a network of donated corpses, I think that aspect might actually be easier for a new reader to grasp in-context here than it was back when it was introduced in Ancillary Justice.
The standalone plot concerns a small planet on the fringes of Radchaai space, which has been gradually falling under the influence of the expanding empire at the point when communications and resource deliveries across it are interrupted by the conflict. As usual the story benefits from the writer's immersive cultural worldbuilding details and interrogation of gender norms, but the core feels a bit farcical despite the impending danger of famine for everyone. Characters scheme and repeatedly ricochet off one another, with a major focus on the local religion and its teaching that people can become living saints by being brought close to death and left mummified in a chamber to await the return of their messiah, which is a literal star. And all this action is narrated to us by some unnamed future scholar, whose playful tone further diminishes the tension and limits us from ever getting too far inside the minds of the various players.
Again: not a favorite given what we've seen from this universe in the past, but an above-average piece of intelligent science-fiction, nonetheless.

I really enjoyed the main trilogy of Imperial Radch books, with Ancillary Justice being the standout, so I was excited to review Leckie’s new entry in the series.
Radiant Star is another standalone novel in the Imperial Radch series, taking place during the events of the mainline series, but on a remote and relevantly unimportant planet. The planet Ooioiaa is occupied by the Radchaai, with a provisional governor, a Justice ship and its ancillaries stationed there. The story follows the perspectives of the Rachaai, local civic leaders, influential religious leaders, and everyday citizens as communication and transportation with the Radchaai Empire breaks down.
I liked the multiple POVs, the worldbuilding of the civic bureaucracy of this planet, and the connection to the main line Imperial Radch story. The POV characters all felt like real people making real decisions in a crisis, and ranged from very unlikeable to loveable. To me, Radiant Star works as a standalone in the universe, but it suffers from a similar pacing and plot issue as Translation State, where the main conflict wraps up in record time at the very end of the book (although Radiant Star isn’t quite as egregious as in Translation State, where the main event the entire book is building to happens off screen). Overall, I found it to be an engaging read and I enjoyed Leckie’s consistently excellent world-building, but found the ending to be unsatisfying.

Apparently there's a meme going around today about six genders because of Dementler mishearing cisgender and going on another dying neuron fueled rant about it. If you were one of the people gleefully swapping memes with all your friends (I saw a fun one with a Sly and the Family Stone album cover) and you're also a Regency fan, you might get a kick out of this book. I think there were easily six genders, along with the agender Justice. This was a new tone for Leckie, and while I didn't love it quite as much as Provenance, it was still a fun read. The ending left me feeling a bit like the "where do we go from here" reprise at the end of Once More With Feeling (entertained but also vaguely dissatisfied) but it was fun to see another Justice and the setting on a rogue planet was cool as hell.

Leckie creates a whole new complex world only loosely connected to the other Ancillary books but it is beneficial to read the other books first to better understand the references in this book. As usual, her new characters & world are well developed but she uses a third party narrative in this book. I would have liked more back story on several of the characters, especially Jonr’s consoror, Citizen Esinu Birit. I feel the consoror must be tied to a character from a previous book but don’t recall anyone who lost an arm. Guess I’m going to have to reread the earlier Ancillary books.

A disappointing tale from one of my favorite authors. Too many points of view, a very small scale of locations, and almost everything that happens is entirely out of the control of the characters involved.

Justice of Albis forever!
I really enjoyed this snapshot into a different part of the Radch universe. People looking for the same level of action as the original Imperial Radch trilogy may be disappointed, but I enjoyed the framing of the book as a piece of the historical puzzle of this world.
Thank you NetGalley for the advanced copy

have you ever read a book that makes you vibrate like a tuning fork????
April 21, 2026
So happy to get an early copy of this book! I am a bookfluencer now.
When justice of albis started showing its personality i remembered why I love Ann leckie. It’s weird to love so many book AI but hate the sycophant robots of the real world.

If you’re wondering where this fits into the chronology of the Imperial Radch, well, so was I. If you’ve not read the Imperial Radch series that begins so marvelously, with Ancillary Justice, you might want to go back and do that. Because DAMN but that opening trilogy (Ancillary Justice, Ancillary Sword and Ancillary Mercy) is AWESOME.
Also it’s the record of events elsewhere in the Radch, the events that are causing so many difficulties on Ooioiaa, the tiny, remote, mostly disregarded and still in the process of being colonized by the Radchaai, the planet on which this story about colonization, colonialism and collateral damage takes place.
In other words, Radiant Star is a bit of a side story to the main action of the series. Or, at least it is from the perspective of the Radchaai governor, her staff and all the functionaries with her on Ooioiaa.
But only until Governor Charak concludes that the weeks she has been entirely cut off from communication and resupply from the vast bureaucratic empire of the Imperial Radch represents, not a mere technical glitch, but a disaster of such epic proportions that multiple gates in the empire’s vast travel and communications network are offline – AT THE SAME TIME.
She knows something terrible must have happened – but she doesn’t have any information to tell her precisely what and how bad the disaster might be.
Without access to the resources that keep both the economy AND, more importantly, the FOOD SUPPLY on Ooioiaa stable, and without the ability to call in “the cavalry” if that stability becomes UNstable, Governor Charak knows that her mission is in trouble.
Not that she doesn’t have enough personnel and especially ancillaries from her ship, Justice of Albis, because if she is willing to be bloody-minded about it she can put down any rebellion on the part of the population. But her mission is to govern these people, not conquer them. Killing a wide swath of those people – if it can be prevented – is against her mandate.
However, between the truly weird planetary conditions on Ooioiaa, the lack of imports from well, anywhere at all to supplement the food supply, a little bit of human stupidity and a whole lot of human greed, the native food supply on Ooioiaa can’t cope with the number of people it is currently supporting.
Inflation and food shortages are not enemies that Charak can negotiate with. She can use the ancillaries to guard what’s left, but her attempts to increase that food supply don’t just fail, they make the situation catastrophically worse.
People are starving on the streets. Well, nearly all of them. If Charak’s attempt to add to the food supply marks the human stupidity that fuels this mess – and it does – then the greed of the local officials who are hoarding food and stealing the little bit that does manage to come in through bribery and outright corruption – turns the whole thing catastrophic.
Fortunately for Charak, the rank corruption of the local officials stinks so badly that a lot of the population’s ire will be turned on them instead of her, once the crisis is over. If it doesn’t end in a planet of graves.
Escape Rating A: This was a LOT. Not necessarily in pages, but in density. There’s a lot going on on Ooioiaa and there’s a lot of story to tell and a lot to think about as that story gets told. Something which was definitely true in the original Imperial Radch trilogy. I think you could start here, because this is very much a side show to the main action of the trilogy. But, but, but, Ancillary Justice sets up this universe in a way that is a bit more focused because it’s filtered through one viewpoint, from a character who is very much learning how things work as they go, so the reader gets to learn along with them.
This story, while it’s to the side of the main one, is absolutely complete unto itself – but it relies on that prior knowledge – even if that prior knowledge isn’t exactly new – to allow the reader to immerse themselves in the story. So you could start here and the story here would work but I know I’d feel the missing-to-me bits floating around the edges and it would drive me bananas. (Your reading mileage may vary on this. I fully admit to being a completist.)
I absolutely did immerse myself fully in this story. This was a one-evening – well, one evening and night – read for me. I fell under its spell in the first chapter and didn’t emerge until I was done after midnight.
Radiant Star is science fiction of the type that Lois McMaster Bujold once described as “the romance of political agency”. While this is certainly about colonialism and colonization, those themes are explored through the people and the political machinations of those people on both sides of the equation. That Ooioiaa is a planet with its own long history, that it has been established and populated for millennia means that its people understand that this is what the Radch is and it’s what the Radchaai do and that they do not have the means to stop any of it. All they can do is attempt to preserve their culture and heritage for a few more generations.
The Radchaai, on the other hand, see the Ooioiaans as mostly civilized but not quite civilized enough. That the Ooioiaan religion includes a LOT of beliefs that the Radchaai find anathema (and vice versa) doesn’t exactly help this situation. That the Ooioiaan religious hierarchy is corrupt down to its bone marrow and fighting amongst its own factions doesn’t exactly make either side more tolerant of the other – but Charak has the power to force the issue. She can’t make the Ooioiaans worship the Radchaai god, but she can co-opt the Ooioiaan religion. That’s ALSO what the Radchaai are good at.
As much as I’ve talked about the situation, because it is fascinating and the workings – and non-workings – of the levers of power fascinate me, the story is told through its characters. After all, the reader can’t FEEL for a system – however intricate – but absolutely can feel for the people being jerked around BY that system. And of course, boo and hiss at the people who are being the jerks.
Which we do. Because there are plenty of both.
One of the fascinating things that we don’t see very often in SF or Fantasy is that a lot of this story centers around the religious practices of the Ooioiaans along with the machinations of their clergy in order to maintain and expand their secular power. Admittedly, the machinations we see plenty of in SF/F, but the actual practices, not so much. In that part of the story, Radiant Star brought to mind The Cemeteries of Amalo sequel subseries for The Goblin Emperor, both because The Goblin Emperor is an SF story, although with a fantasy feel to it, that is very much about political agency and political power, and because The Cemeteries of Amalo series which begins with The Witness for the Dead, views that world through the eyes of one of the members of its religious orders, someone who is themself a true, righteous believer but sees their superiors for the humans they are and their jockeying for power and positions as the distractions from faith that they have become.
The ending of this story tied the whole thing up in a bright, shiny bow that also looped in EVERYTHING that happened in the original trilogy AND swept up all the religious and political loose ends in a way that was the best kind of deus ex machina. Because the machina isn’t deus at all – it just has really excellent timing. Bringing this fascinating epic to a grand AND hopeful conclusion.
Just as hopefully, I hope that this is not the end of the Imperial Radch sequels. Because the three we have so far, Provenance, Translation State and now Radiant Star, have all been VERY worthy successors to that landmark (maybe that should be spacemark?) award-winning series and I would love to have MORE!

The review aims to be as Spoiler-free as possible.
Ann Leckie’s sprawling space opera juggernaut Imperial Radch continues with another standalone story, Radiant Star. A winding tale of religious fanaticism, opportunism, and the perils of faith set against the backdrop of a divided Imperium.
Like everyone else, I was a massive fan of Leckie’s original Imperial Radch trilogy. A sprawling space opera of interstellar hegemony, with stinging commentary on cultural invasion, artificial intelligence, and the iron hand of imperium. A few years later, I was glad to hear that the author was continuing to write standalone novels set in the world of the original trilogy, telling smaller scale stories tied into the main themes of the trilogy. I mostly enjoyed Translation State but missed the grand scale of the Ancillary trilogy. Radiant Star follows in the same vein, telling an original story set during the crucial events in the mainline trilogy, albeit to explore its far-reaching effects at the very edge of the Radch.
As the title suggests, this standalone revolves around the titular Radiant Star, a religious icon on the underground city-planet of Ooioiaa, a tiny spec at the edge of everything important. The residents of this city, subject to their own religious fervor, and politicking that goes along with it, continue to wrestle for power; both metaphysical and mundanely capitalistic. When the Radchaai inevitably arrives and adds the planet to the Radch empire, the governor realizes this will not be a regular assignment. The governor has to deal with balancing the cultural status quo among the native people while still maintaining the imperial hold of the Radch, all while interceding with local power struggles, among the various religious sects and business interests.
We are introduced to several POV characters in Radiant Star setting up the board in Oiioiaa, a newly elected religious heirach, a fanatical oligarch determined to enter sainthood leaving his estate in a tumultuous inheritance power struggle, a religious zealot with his own internal (and external conflict) of faith, and a lonely boy, cast aside from society and fate, merely finding a way to exist in this strange place.
I have always deemed the Imperial Radch series as a grimmer and darker version of Iain M. Bank’s Culture universe. While the Culture is a post-scarity utopian empire, the Radch is your standard fare of wartime dystopia. However, many themes of cultural diversity across various social issues are usually the focus of these books, and Radiant Star is no different. Leckie continues to spearhead her efforts of inclusivity as a central tenet of her books, giving our present world its own star to follow in these matters. Her strict adherence to using various genders and representation, down to a range of pronouns and identities as a commonplace aspect of both her narrative and narration makes these aspects feel normal, a clear indicator of a more broadly liberated society.
Unfortunately, the story of Radiant Star is a largely predictable one, and explores themes not entirely unkown to fans of these kinds of far-future stories. An exploration of the cultural clash between an advanced technological society like the Radch and smaller culturally rooted societies is a notable trope in the genre, though Leckie does a good job to bring out the human nuance through various character motivations, altruistic, nefarious, opportunistic, and plain old survivalistic. There are nods to the greater Imperial Radch series, as this novel is set during the events of the mainline trilogy, and keen readers will spot the references easily.
Overall, like Translation State, I mostly enjoyed my time with Radiant Star, and I hope Ann Leckie continues to tell more stories in this universe, making the Imperial Radch series as sprawling as the empire itself.

Leckie continues to spearhead her efforts of inclusivity as a central tenet of her books, giving our present world its own star to follow in these matters. Her strict adherence to using various genders and representation, down to a range of pronouns and identities as a commonplace aspect of both her narrative and narration makes these aspects feel normal, a clear indicator of a more broadly liberated society.
Unfortunately, the story of Radiant Star is a largely predictable one, and explores themes not entirely unkown to fans of these kinds of far-future stories. An exploration of the cultural clash between an advanced technological society like the Radch and smaller culturally rooted societies is a notable trope in the genre, though Leckie does a good job to bring out the human nuance through various character motivations, altruistic, nefarious, opportunistic, and plain old survivalistic. There are nods to the greater Imperial Radch series, as this novel is set during the events of the mainline trilogy, and keen readers will spot the references easily.
Overall, like Translation State, I mostly enjoyed my time with Radiant Star, and I hope Ann Leckie continues to tell more stories in this universe, making the Imperial Radch series as sprawling as the empire itself.

Radiant Star is part of the Imperial Radch series, but a stand-alone. While it’ll work best if the reader knows the world and the previous events, it can—to an extent—be read as a stand-alone too. It’s set during the timeline of the original trilogy, but it’s only tangentially touched by those events.
Planet Aai is drifting in space without a sun, completely encased in ice. But it’s inhabited, and the city of Ooioiaa is a thriving underneath the ice. The ecosystem is delicate though, and the planet is heavily dependent on outside provisions. The culture and society are delicate systems too, which the Radchaai discover a bit too late after they conquer the planet.
Thirty years after the arrival of the Radchaai, the planet finds itself cut off the rest of the universe. Since there’s no communication and no way to travel in and out of their space, they don’t know what’s happening or how long it’ll last, and there are no provisions. The Radchaai governor realises that food will soon become scarce and introduces the Radch food stable, a fast-growing algae, into the ecosystem. At first, it works fine. And then the ecosystem collapses and the governor has a famine at her hands.
The governor has other problems too. The local religion that worships the Radiant Star, waiting for its return, is fractured into sects that are constantly fighting, and she has to share space with them. An introduction of the last saint—a practice the governor is trying to end—pushes matters to a point, destabilising an already fragile society.
Within this framework of a city on a brink of collapsing, three people emerge. Speaking Savant Keemat, who becomes convinced that they should be the last saint; Jonr, a neglected son of a consoror system who was supposed to be shipped out of the planet before the Radchaai arrived, but who has been stuck in a stasis pod for three decades, only to emerge to a changed world with no place in it; and Iono, whose father is supposed to be the last saint, which pushes him into a personal crisis and questionable choices. Other characters feature too, but these three are the main stories. Everything is narrated by an all-knowing, unknown person years after the events of the book.
The stories are, in a way, about small personal goals that either work or fail. They don’t come to a point simultaneously, and only Keemat gets the ending they wish and work for. Iono, who isn’t a very likable character, gets what he has coming, but also not. Jonr’s story is the one I had highest hopes for, but it ended up being the most neglected one. It doesn’t really lead to anything but a status quo for him, nor does it have any impact on the overall plot. We don’t even get a last chapter or epilogue from his POV, nor do we learn what had happened to the consoror he’s in charge of.
The chaos that the planet finds itself in comes to a surprisingly peaceful closure soon enough. Nothing much changes on the planet in the end. The Imperial Radch has changed, but that doesn’t really impact the story here. All the solutions to the governor’s problems seem a bit like deus ex machina, as the narrator divulges information as they see fit, the actual plot happening behind the scenes. Most of the time, the plot was revealed backwards, after the fact.
This was perhaps the simplest, most straightforward book in the series so far, and most readable and easiest to follow. Ancillaries featured, but weren’t a POV character, so there were no complicated scenes where the reader had to follow many events at once. The plot was simple, about the consequences of meddling with the ecosystem. The characters were mostly grey and a bit difficult to root for, except for Jonr who deserved all the best. The problems solved fairly easily and I kept waiting for the other shoe to drop, but the book ended.
This was an engaging book, but it wasn’t mind-blowing like the previous ones have been. But anything Leckie writes in this universe will interest me, and I’ll definitely read more.

Review of advance copy received from NetGalley
My thanks to NetGalley and Orbit Books for an advance copy of this science fiction novel about a planet, its people and their beliefs, and how a simple matter of a person wanting to be more than just a business leader and more of a holy person, opens up a whole can of worms for many including members of a vast interstellar empire who are occupying the planet.
My love of science fiction came from television and movies, and maybe comics. Star Wars and Star Trek were big things for me. The movie blew my mind, the show kept me entertained. I remember reading the novelization of Star Wars, bought at my Scholastic book fair, and reading the Star Trek Logbooks, story form versions of the television show, found at a book sale at about the same time. The showy Star Wars gave me a love for aliens, battles, and well more battles. I liked Star Trek for the battles, but the deeper storylines escaped me. As I got older these two space battles, and better tomorrows began to merge, as the ideas of science fiction, the worlds being created, the futures being formed and of course the people began to mean more to me. Ideas that this author use to create such amazing stories, stories that while exciting and interesting, make one think and wonder. Radiant Star by Ann Leckie is a stand alone novel set in the Imperial Radch series, about a planet occupied by the Radch, going through a series of upheavals, both culturally and spiritually, all while the Empire that occupies them, begins to break-down in many different ways.
Ooioiaa is a city, the largest and only city, on an impossible world. A world without a sun, one covered in ice and ground, deep inside the planet. The people don't know why the colony even exists, being so hard to get to, and to set up. This means that space is at a premium, and that those who build can make vast amounts of money. In this city are a variety of people. One wealthy woman grew bored of life in Ooioiaa and left for a time traveling the universe and returning not only with a lot of wealth but pregnant with a child. This child did not know that it was different, but felt it in the way that it was treated. When the child came of age, it was told that it was promised to be a servant on a far distant world. This did not sit well, so the child took off into the vast tunnels under the city. As this was happening, a rich man decided that death was too much, and that sainthood in The Temporal Location of the Radiant Star would be quite nice, a decision that not only effected his son, but cause dissent in a world already short of room and resources. All this while the Radch occupiers find themselves out of communication with their vast empire, and alone on a frozen world, that seems to be getting very hot with tribulations.
A big sprawling book, loaded with ideas, not only science, but cultural, spiritual and geological. Leckie has created a small world, with a lot of problems, and made it even worse with the appearance of Radch. This book takes place during Leckie Ancillary series, something the characters have no idea is going on. The writing is of course very good, with lots of well-developed characters. The ideas are really the best part, the idea of the religion, the way servants are chosen, and even little things that add not only realism, but make the reader want to know more. As with most Leckie books one has to find the mindset to get into the books, so familiarity helps. However it is not necessary to have read any previous books, though it helps, and why deny oneself some very good stories.
The book moves well, and once the characters and setting are set into play, the narrative flow carries the reader along. For a big book, one has a hard time putting it down. I continue to be amazed at the ideas that Leckie comes up with, and make so real. Another book for fans, and though it might take a few pages, a good one for new readers.
