This was the third of this series, and for various reasons, I think there will be more.
I certainly hope so, I think this is the best new science fiction of the past year or two. The Sun Eater series is good too, but I prefer Arcana Imperii, it has a better spaceship coefficient!
An interesting development was that Marca Nbaro wasn’t the main character, instead I found myself rooting for Thor Storkel who only got mentioned as a good pilot in the first two books. I like the concept of changing the main character, it adds variation, and since Miles Cameron is so very good at character building, you get a new nice character, and also get to keep the old ones.
The downside is that books like this get very complicated, I ended up reading all three books again, so as to keep up. All three were just as good, or maybe even better on rereading, you notice things that you miss on a first reading. I’ve previously complained about “imperfections, repetitions, ideas that don’t really hang together”, I don’t recognize that at all in this book, I think it’s well written.

A curiosity Thor Stöckel is a Swedish ice-hockey player, I wonder if Miles Cameron has been dipping in Swedish hockey history to come up with the Thor Storkel name?

Anyway , this is a super good book, very engaging, exciting and often quite funny, the crew banter is fun, and there is a lovely twist at the end. Highly recommended for a nice easy read, despite what I said before about complicated, it’s good complicated.

I was pleased to see this one arrive for review – after all, this series has been one of my favourites in recent years. (The two books so far - Book 1, Artifact Space, and Book 2, Deep Black - have been in my ‘best of the year’ lists in both 2021 and 2024, for example.)

Whalesong, Book 3 of the Arcana Imperii series, follows on immediately from Deep Black (and therefore there are minor spoilers here in this review for Book 1, Artifact Space, and Book 2, Deep Black .)

Although Deep Black clearly tied things up with one story arc (the huge battle between the Directorate of Human Corporations (DHC) and the PTX, and Nbaro’s ascension in political power), Whalesong begins another story arc, as it follows on immediately from the end of Deep Black.

It also means that although Whalesong is the first part of a new story arc, it is not the story to begin with in this series – there are revelations here that will mean little if you haven’t followed what has gone before – but if you have, you will be rewarded.

We start Whalesong with Marca Nbaro & Horatio Dorcas adjusting to a life back at home base and also married life. Dorcas becomes obsessed with salvaging an alien Hin spaceship, now lifeless yet intact outside the Kuiper Belt of Ultra-Medulla and travelling out of the galaxy. We also have Nbaro arranging for a whale to be transported to communicate to the alien Starfish, as this was one of the alien’s requests in Deep Black.

My initial thought was that this would be the main plot of the novel, although this third book actually focusses away from our main characters to date, to focus on Thor Stokel, their friend and ex-colleague. Thor has retired from active duty and is now (thanks to some actions of Nbaro and the AI Morosini) the captain of the Silver Star, a refitted spaceship and is able to be a merchant spacer, trading across the galaxy.

This means that the next part of the novel is rather like a Heinlein-esque travelogue as Storkel travels from planet to planet - anyone who knows the classic computer game Elite will get the idea. Storkel also has to assemble a crew for his new spaceship. He employs Cawo Elmi-Mahmoud as a competent second-in-command and the enigmatic Badal-Mehra as an astrogator. When Marca ends up in hospital, Dorcas later joins the crew, as well as Feyyan Zhao as a weapons officer, despite Zhao being a person with connections to the PTX, (a competing group to the DHC.)

As is typical of this series so far, all of the main characters are interesting. Storkel himself is particularly noticeable, because knowing himself to be paranoid (a result of the battles in Deep Black and the drugs taken to cope with high-g manoeuvres) he questions everything – his ship, the AI, his colleagues and himself. This leads to difficult choices being made more challenging as he thinks or even overthinks every decision – for example, is the ship’s erratic AI working with him, or against him?  Can it be trusted to do what it is asked to do?

Furthermore, as he delivers goods around the galaxy, Storkel finds that others want him dead, for reasons that evolve within the story. The last part of the book is a tense and exciting chase with everything to lose.

To counterpoint this, Dorcas, as seen in Deep Black, is this book’s Spock – often aloof, always questioning, his connections with the AI through a neural lace and his work to communicate with the alien Starfish in Deep Black which is paramount to this story.

With that in mind, then, Whalesong deftly juggles political intrigue, philosophical musings, and space battles at a ridiculously high speed, but using proper science and math. There’s espionage, deep cover exercises, loyalty and treachery involved, all filtered through Storkel’s increasing paranoia that keeps things moving and the reader questioning everything.

As befitting a story from a master plotter and storyteller, it is well done. I did feel that, as good as it was, the previous novel (Deep Black) sagged a little in the middle with its endless descriptions of space travel in an enclosed environment. I’m pleased to say that there’s no such issues for me here.

Although the story (as before in the first two books) is centred on a few characters, Miles is adept at also playing the long game. I liked the fact that although the story focussed on a relatively small group of characters, there are bigger issues at stake, although most of these are still unresolved. The last few chapters, as with Deep Black, bring us back to the bigger picture and set things up for the next book. There are clearly more revelations to follow – in fact, book four is due in 2026.

In summary, Whalesong continues to show the author’s strengths in characterisation, pace and plotting. It is a tight, fast-paced and shorter story that effectively builds on what has gone before, before leaving with a humdinger of a cliffhanger ending.

The thing Miles Cameron consistently gets right in this series is scale through infrastructure. Even when the plot slows down or becomes tangled in politics and operational detail, the universe itself always feels immense, functioning, and heavy with history. Whalesong continues that strength, but this time the atmosphere felt more focused and immersive than Deep Black did for me.

There’s a strange loneliness running through large parts of the book that really worked. Deep space in the Arcana Imperii universe doesn’t feel adventurous in a romantic sense; it feels cold, distant, procedural, and full of systems barely holding together under political pressure and technological uncertainty. Cameron is very good at making interstellar civilization feel fragile despite its size.

The artifact material remains the most compelling aspect of the series by far. The deeper humanity digs into ancient technologies and incomprehensible remnants of older powers, the more unsettling the universe becomes. Some of the sequences involving exploration and discovery genuinely recaptured that feeling of cosmic mystery the earlier books hinted at so strongly. Cameron understands that ancient technology becomes much more interesting when it feels partially unknowable rather than conveniently interpretable.

And honestly, the ships themselves are still fantastic. Few modern space operas put this much effort into operational realism. Maintenance, logistics, command structures, navigation, resource management, military procedure—it all creates the sense that these vessels are functioning societies rather than cinematic backdrops.

Marca also felt stronger here than in the previous book. There’s more emotional weariness to her now, more awareness of how trapped she is inside competing systems of power, obligation, and secrecy. The series works best when it leans into that tension between personal identity and institutional machinery rather than simply escalating military conflict.

At the same time, Cameron still hasn’t entirely solved the pacing issues that have followed the series from the beginning. There are sections where the narrative becomes so dense with procedure, terminology, tactical discussion, and political maneuvering that momentum nearly stalls. Sometimes that complexity creates immersion; other times it feels like the novel is fighting the reader unnecessarily.

The characterization can also remain oddly distant. Individually, many characters are interesting, but emotional moments occasionally get buried underneath the operational detail and institutional complexity surrounding them. There were scenes where I understood the political stakes intellectually while still feeling somewhat detached from the people involved.

But compared to Deep Black, this one felt more balanced overall. The mystery elements had more pull, the atmosphere felt sharper, and the quieter moments aboard ship carried more weight. The series seems strongest when it embraces uncertainty and isolation rather than trying to constantly expand into broader strategic complexity.

What I continue appreciating most about these books is that Cameron treats empire as labor. Not mythology, not aesthetic spectacle, but maintenance. Supply chains, exhausted crews, decaying systems, political compromise, inherited structures nobody fully understands anymore. The universe feels old in a believable way.

There’s also something refreshing about how unapologetically dense the series remains. It absolutely demands patience from the reader, sometimes more than necessary, but that density also gives the world texture that a smoother, more streamlined version might lose.

For me, Whalesong felt like the series recovering some of the intrigue and atmosphere that made Artifact Space initially so compelling. Still imperfect, still occasionally overcomplicated, but much easier to get absorbed into once the mystery and isolation start taking over the narrative.

When I read Miles Cameron's Artifact Space back in 2021 I was very impressed - somehow, I've not kept up the author who, for me comes closest to Alastair Reynolds in writing intelligent, engaging space opera. As a result it was a delight to return to the Artifact Space universe with the third book in his Arcana Imperii series. (I've also added book 2 to my reading list).

Cameron shines by giving us both a complex political background and genuinely likeable central characters in the small crew of what initially seems to be a simple freighter but ends up being far more. Although not a direct parallel, for me Cameron gives the same warm feeling that fans get from the best of Star Trek, with the opportunity a novel provides to give significantly more depth. It was simply a joy to read.

My main complaint with Artifact Space was the length - thankfully this volume pulls back from the wrist busting 568 pages to a more modest 406, much to its benefit. The central character of the first book, Marca Nbaro, is more in the sidelines here and we get a new crew - in fact the only time I was a little irritated with the book was when the storyline flicked back to Nbaro, simply because I was so invested with the central crew, I didn't want to lose their story for a minute.

Another strength here is the use of AI characters - with some highly relevant thoughts about the dangers of putting AI in charge coming through in a subtle way. However, this never gets in the way of the very human, straightforward adventure of the story arc, with a couple of impressive space battles. This isn't a book trying to put across a message (thankfully) - it is just pure, engaging entertainment, which is not a bad thing.

My only other small moan is more technical. There is no mention of shields or the equivalent to protect ships - a lot of the damage in battles is done by conventional projectile weapons. But we also find out that it's possible to exit from artifact space, Cameron's hyperspace-like solution to interstellar travel, at high speeds - at one point 0.2c is mentioned. Tank shells travel at around 1,700 metres per second - That's around 35,000 times slower than 0.2c. A 1 gram speck of dust would have the same impact as a 35kg shell at 0.2c. At that kind of speed, shields would be essential.

In the end, though, this can't get in the way of an effective page-turner at the very peak of space opera delight.

After the fantastic book #1 and the very good book #2 this was a total misfire.
With all the interesting mysteries we have yet to solve that were started in book 1 and 2 how the author could totally disregard those and tell a meaningless, small, boring artificially inflated story that ultimately did not contribute to the universe at all is beyond me. Nothing happened, nothing developed, nothing progressed. It does not even have an ending it just fizzles out. What are we doing here?
This should have been a short story or novelette, these is not even enough there for a novella and certainly not a main entry in the series.
Not sure if I want to continue with the series.

I LOVED Artifact Space and Deep Black but for some reason I found it hard to click with Whalesong. I read approx 20% but I felt no connection to the characters nor did I jibe with the plot (and this type of storyline is what I truly love about a number of Space Operas - I did read a large # of S.O's last year so maybe i just need some time away)
I have put in on my "Try again sometime" shelf, so have put it down the tbr mountain range for now. Miles (Christian) Cameron is high on the list of authors I enjoy, hopefully I'll return to this later in 2026.

Not as good as the first two books in the series, but still quite riveting.

Even though Nbaro is on the cover, this book is not about her. Nbaro only has a few cameo scenes and spends most of the book off in a healing clamshell. The book really focuses on a minor character in the first two books who is now the main character.

If I had to sum up the book in a sentence it would be "spies in space." The whole book is a fascinating deep dive into paranoia and who is on our side and who can we trust and what plots are afoot. It's a real page turner that I would highly recommend.

This book falls into the category of books in which several things are unbelievable/don't work and yet no one cares about the impossibility because we're all so entertained. The first two books were like that two, but this book was a little less believable in a way which took me out of the story just a little bit. Two things hit me the most. Without giving anything away, I present this hypothetical: Let's say I leave San Francisco in my car at maximum speed towards Seattle. Mid-way through the trip it becomes clear that I'm being chased by assassins who are also traveling at max speed. San Francisco then dispatches a car at max speed (the same max speed) to rescue me. Somehow the rescue car is able to arrive at the conflict while the conflict is still going on and not wildly after. Doesn't work, does it? Secondly, it drives me nuts that they always launch sand during space battles. I think a spaceship traveling through sand at extreme speeds would be disabled in the same way that straw in a tornado goes through telephone poles. Also, the sand isn't going to go anywhere. It will persist. Therefore, spreading sand seems like it would make entire regions of space impossible to travel through ever again. That said, again, no one cares because it's just so much FUN to read.

I can't wait for the next book in the series.

Thank you to NetGalley for a free copy of the book!

I must say, many of my recent contemporary SF reads have reignited a spark of hope for the new SF genre. Miles Cameron's writing style is amazing, and it gave me cause to appreciate all the complexities of DHC politics and even the perils of Storkel's own shots at independence. I think Whalesong avoided clichés in a way that didn't sacrifice the theater of political intrigue. I've definitely also come to appreciate political intrigue in space. Earlier on in my reading, I probably wouldn't have held the same outlook, and it helps, again, that it's delivered so tastefully. I will also add (on a personal level) that Storkel's paranoia was delicious to read. I appreciate textured characters, especially in a genre as trying as science fiction. So, I had no qualms following his story across Whalesong, and I appreciated Nbaro's entry into an entirely new political sphere earlier on.

I'd have liked it if a few more loose ends were tied before the last page. That aside, though, a great read!

Eine gelungene Fortsetzung, die jedoch die Qualität von Band 1 und 2 nicht ganz erreicht.
Die Struktur und damit das Pacing funktionierten für mich erst in der zweiten Hälfte wirklich.
Das World building und die Story ist aber weiterhin großartig. Interaktionen zwischen Figuren fühlen sich sehr real an. Vor allem aber die sozioökonomischen und politischen Geschehnisse sind wirklich gut beschrieben und nachvollziehbar.
Die Welt fühlt sich lebendig an.

I thought this was going to tidy up the story in a neat conclusion but instead the universe got a whole lot bigger. Can't say I'm unhappy about that.

This third volume of the Arcana Imperii series introduces a new set of characters and gives us action much more reminiscent of The Expanse than Honor Harrington. That is a good thing. Cameron does a fine job of detailing the physical rigors of space battles—acceleration, radiation, and long periods of high tension.
Whales come into the picture because Dorcas hopes to use them to communicate with the aliens humans call starfish.

Review of advance copy received from NetGalley
July 25, 2026
Whalesong takes off right after the end of book 2 Deep Black. While Cameron does give enough context that a reader could pick up book three independently, I think it's far more enjoyable to have read books 1 and 2.

So as this is book 3 in a series, there are going to be some minor spoilers, but I will attempt to not give away any of the excellent plot.

The set up in this book was a bit slower than the first two- Our crew is now free of their contract, and readers find them pursuing multiple different lives - some outside of service, and some taking on new roles across the universe. Up until about 40% I felt like I was actually missing some of the crew, but Cameron of course, brings things full circle and the narrative really sped up at about 50%- and if I am being honest, without the slower set up in the first half of the book, the second half would not have been as easy to follow and I would not have had as much fun as I did with it. I will particularly say there is a moment when Zhao- a character who seemed to be basically a supporting character, rose to Main character status, and at that point, I just feel in love with her and the entire plot. At that point, I found it hard to put down and I had to finish. I did feel that this is an excellent series to turn into a TV drama (anyone listening?)

What can readers expect?
- An extension of this Space Opera with introduction of some new players. Continued growth and development of characters we already know.
- Well written, pulse pounding action and battle scenes
- An underlying very human love story
- Hard Sci- Fi elements of insertion points, space fuel, space weapons, the realities of gravity and space travel and more.
- Military Sci-Fi elements- political intrigue, battle strategy, space weapons, alliances and spies.
- Soft Sci-Fi elements focusing on deep character development, relationships, ethics and linguistics in a space setting.

I very much enjoyed this one. If GR gave half stars I would put this at a 4.5 but since they do not I am rounding it up to 5 stars on vibes alone. I fear I am going to be in a big slump when this series is complete.

This is the third book in Miles Cameron's Arcana Imperii Series, and it is a marked deviation from the prior focus and style of the first two. I loved the first two books for what I call "competency core." This sub-genre has a character(s) who are really badass at a skill, but retain doubts and fears and anxieties. Murderbot is a well-known example of this, in my mind. In the first two books, Marca Nbaro was that person: she escaped a dangerous life to live a life of deception onboard a merchant marine type Greatship, and ended up lucky and a heroine while also becoming embroiled in the future the AIs had been steering her toward. I read these books obsessively, unable to put them down. I re-read them happily for this sequel.

The third book isn't like the first two, but it's still really good. Just different. Instead of following Marca exclusively, we spend time with a cast of new (and some old) characters. I wasn't sure about this; sometimes change is hard. I chose to trust Cameron to tell a good story, and he does. This book felt like a necessary stepping stone in the overarching plot of humanity gearing up toward the big war to come. Instead of making that step a footnote, Cameron chose to expand it with a story and a crew who learn the unfolding plot at the same time we do. It's good to have an author I trust who revels in the sandbox he's built.

I feel like this book gave Cameron a chance to show his skills at character work. We are given a man from the earlier books' battles who now is suffering PTSD, but has always dreamed of owning his own spaceship. He doesn't really know what he's doing though, and this leads to dangerous adventure. Each new adventure pulls in another character, and deepens the plot aiming us toward the big reveal. Overall, I'll admit I longed for the buzz of a character getting everything right by luck or grit. This is the opposite--a character getting it mostly wrong. It's still entertaining and emotional, but in a very different way.

I will say that the title of this book feels misleading, and the given premise of the book is a red herring. Be forewarned if you are picking this up based on that title alone.

It's good to know that Cameron has more than one trick to show us, and I look forward to reading the rest of the series!

Thank you to NetGalley and Saga Press for an e-arc in exchange for an honest review.

This is a tough one to rate. The series has been great and this was a solid installment. Did it feel a bit like a middle book? It did — there was a fine story here, but ultimately it only moved the high-level plot forward enough to set up the next book. But that’s not what cost it a star for me. And honestly, I’m being a little unfair — I just have to find some way to say that while this was great, it didn’t blow me away like the first two did.

So: it was fun to spend time with some other characters. There was enough actual time with Nbaro and Dorcas to be satisfying, while others led the story. But, I guess I have a few issues, which individually are minor, but kind of added up? First the plot was a little scattershot, with a few different stories separated by a decent amount of space and time. It all fit together, but I’d have preferred not to jam them all into one book. And for the most significant part of the story, I’d really have liked Zhang to have a still more prominent role. Next, by the end I’d have liked more insight into the antagonists: . And finally, for a book that’s had quite a lot of convincing space combat… I needed better justification for .

Bottom line, in any other series this would have been five stars, but the first couple set the bar too high and this wasn’t quite at the same level for me. Nevertheless, I’m absolutely going on to the next (final?) book as soon as it’s available.

Review of advance copy received from NetGalley
April 4, 2026
3.5 rounded up because despite my issues with this book and disappointment after the first two novels in this series, I still enjoyed this book enough.

What worked for me:
* Focusing mostly on new characters and some characters who played a background role in the previous books.
* The big reveal at the end (I wasn't sure at first how I felt, but you know what, I'm satisfied with it).
* It was kind of interesting seeing some lower-stakes (or sometimes not) interaction on various stations & worlds.

My issues:
* It felt like this book didn't quite know what it wanted to be. Given the major questions left hanging at the end of Deep Black, this book mostly seemed like filler. And yet, there were some pretty important reveals here that mean you can't really just skip this book. But the "filler" material makes up the bulk of the page count. I think I would've enjoyed this book more had it been shorter.
* Along the same lines, Marca's storyline here -- notably, this time a secondary plot -- was confusing to me, probably largely because we got the story only in small chunks scattered throughout the book with a lot of intervening time spent elsewhere.
* Some of the same irritating sociopolitical biases of the author that make appearances in Beyond the Fringe also bleed through in places here. The heavy-handedness isn't quite enough to make me deduct more stars, but it's enough to make me roll my eyes so hard they leave my head.

✦ Book Review: Whalesong (Arcana Imperii #3) by Miles Cameron

✧ ᴛʜᴀɴᴋ ʏᴏᴜ ꜰᴏʀ ᴛʜᴇ ꜰʀᴇᴇ ʙᴏᴏᴋ, @SimonBooks

➤ 𝚂𝚈𝙽𝙾𝙿𝚂𝙸𝚂

Following the events of Artifact Space and Deep Black, Marca Nbaro finds herself navigating an increasingly dangerous political landscape as humanity faces threats from within and beyond its borders. Espionage, terrorism, shifting alliances, and the lingering danger of an alien war all collide as a single merchant vessel once again finds itself at the center of events that could determine the future of the Human Sphere. Cameron continues to expand the universe while raising both the personal and galactic stakes.

➤ 𝚃𝙷𝙾𝚄𝙶𝙷𝚃𝚂

Miles Cameron continues to prove why this has become one of my favorite modern space opera series. What I enjoy most isn't just the action, but the confidence with which he builds his universe. He trusts the reader to keep up, weaving together military strategy, political intrigue, and large-scale science fiction without ever stopping to overexplain every detail. That makes the world feel believable and lived in. Marca remains a compelling protagonist, growing naturally as the responsibilities on her shoulders continue to expand. Like the previous books, this isn't a fast, popcorn-style adventure. It's a story that rewards paying attention, and the payoff is well worth the investment. If you're new to the series, don't start here. Read Artifact Space first and enjoy watching one of the more thoughtfully constructed science fiction universes unfold.

Thank you NetGalley and Saga Press for an advance reading copy of this book.

World building: 5 stars
Characters: 5 stars (no aliens this go-round)
Plot: 3.5 stars (it’s a little like interlinked stories)
Overall: 4 stars

With Whalesong, we return to the world established in Artifact Space, Deep Black and the collection of stories, Beyond the Fringe. The world is complex, with well defined politics, technology and believable factions.

The structure is a little more like linked stories than either Artifact Space or Deep Black. We have several different POVs, that mostly join up at the end. I think that Qaqqaq’s episode felt a bit unfinished, as they go off on a mission, then we next see her back, without any discussion of what happened. That’s the reason I didn’t feel this one was a focused as either Artifact Space or Deep Black, both of which are tightly centered on Marca Nbaro.

However, the introduction of Storkel and his crew on the Silver Star successfully continues the space opera of the first two novels.

Overall, I really liked it and want more in this world. Because Marca and Dorcas aren’t on Athens any longer, we are likely to have continuing diverging plot lines. As a story collection, Beyond the Fringe had short episodes with different characters in each story and worked well, but in a novel, I think we expect either a single plot or a convergence.

After going big in the last book, I thought this one was going to go bigger and focus on the politics of the Human Sphere since Marca has married into a rich, influential, political family. Instead, this book went small. It largely focuses on Thor Storkel, a pilot and friend of Marca's, who buys a ship of dubious provenance and tries to become an independent freighter captain after retiring from the merchant fleet.

Storkel tries to get by without any crew at all but quickly realizes that this idea is slow suicide. After being cushioned from some of the power plays, bribes, squeezes and paperwork of the merchant world by being part of the gigantic Fleet, he's got a lot to learn. Slowly, Storkel begins to build a tiny crew (perhaps four or five people all told), acquire a ship's cat (the cat lives!) and make some contacts that promise repeat business. But he might not be quite as done with the fleet as he thought...

I liked that entire plot line. Marca's plot line felt kind of shoved in to give her something to do without making her too powerful yet. Also, I could have used more whales. The author's still got his masterful touch at building tension and presenting mature, competent people as characters.

Whalesong and its two predecessor volumes are easily the best space epic I have read in years. Miles Cameron is an exceptional storyteller with seemingly unlimited imagination, as well as a very talented writer who constantly challenges with sophisticated ideas and eloquent language. His character development is rich and compelling, introducing several new members to the cast in this tale, a welcome addition in my estimation. I especially appreciated his use of their interactions in the long intervals predicated by space travel itself, as a mechanism for the evolution of the relationships amongst their group. The interwoven political intrigue, action-packed battle sequences, impacts of artificial intelligence (both allied and malign/evil), aliens, and detailed day-to-day life in deep space all paint parts of the background that bring this story to life. A worthy addition to the Arcana Imperil tale, and a well crafted basis for additional episodes to the saga should they be forthcoming. To me, simply a masterpiece.

Nice review at Locus:
https://locusmag.com/review/whalesong...
Excerpt:
"What I most enjoy about Cameron’s series is the joy of adventure. The novels are set against a galac­tic backdrop – faster than light travel exists but the distances are still vast, with trading voyages easily lasting a year or more. Humans are spread across a vast number of planets. With Thor so focused on the mercantile side of things as a sole trader, Cameron gets to explore more of what it’s like for individuals within this society; and in particular, what it means for the DHC to be directing the trade and fiscal systems. ... Marca, Thor, and their friends continue to be immensely entertaining."

Also some very positve reviews from trustworthy GR Friends. High priority TBR!

While in many ways this is a filler episode in this series of books, acting as the bridge between the first arc and what looks to be the second, it was still an utterly engrossing read that I finished in less than 24 hours.

I realise that I am a total sucker for Cameron's habit of writing characters that fit the same broad arc. They are talented, but also work very hard. They surround themselves with similar people and then, often acting as an informal group, work on some form of grand plan to save the world/universe because their personal sense of honour/morals dictates they should.

It's the same model he uses, to a greater or lesser degree, in all of his books, and I love it unashamedly. Reading about morally complex people who work hard to overcome problems is very satisfying.

I really enjoyed the first two books of this series and was looking forward to this one. However, it did not live up to my expectations. This book very much felt like it should have and could have been a short story rather than a novel.

Not much time is spent with Marca, even though the first two books were focused on her and her character development. As well as mostly ignoring the original characters, this book also ignored most of what the original two books set up for and focused on.

I don't recommend this one and was certainly disappointed by it. My thanks to NetGalley and Saga Press for allowing me to read this work. All thoughts and opinions expressed in this review are my own.

I reserve 5 stars for the books I know I'll read again and again. As soon as I finished this one, I wanted to turn right around and start the trilogy from the beginning.

The first time through, I was swept up in the story. The second time, I know I'll be paying closer attention to the characters, the subtle details, and the deeper philosophies woven throughout.

Miles Cameron is an exceptional writer. His characters feel real, his storytelling is immersive, and his command of language elevates every page. This trilogy has earned a permanent place on my reread shelf.

P.S. I listened to the audiobook read by Nneka Okoye. She is superb.

Found Zhao to be an annoying cliché, Storkel was not that interesting, except for his background and how he became a space pilot. And didn't get the Storkel-Zhao thing. Some elements were interesting, but this volume wasn't as good and 1 and 2. I love the 'lived-in' tone of this universe eg. the very sketchy and scruffy nature of Aleph station and the culture there, the cultures of each human-settled station and planet. And how each space vehicle seems very functional and lived-in, too. Artifact Space blew my mind, love the character of Marca Nbaro. But these books, including Whalesong, were good space opera and entertaining.

Carries on a great story and this is my favourite series amongst all Miles Cameron's books, across all his pseudonyms.


Very grounded, very realistic. The opposite of young adult, and the opposite of fantasies set in space, ie. Star wars.

For example, when some spacecraft are in the middle of extended combat, it talks about them going into a merge, a highly technical term commonly used in fighter jet combat, which makes so much sense here, and he extends it to make sense in this context too. Love the verisimilitude!

This is a 3.5 star review for what rightly should have been book 2.5 of arcana imperri. Cameron remains engaging as a writer of space combat. The plot here is very slight and does not fundamentally change the situations of our heroes by the end.

A couple of complaints
1) the opening chapters are almost completely superfluous to the narrative and written in weird, almost staccato, way

2) I rolled my eyes at the reveal of one of the characters identify. This is a big universe and it is too pat to have everyone know each other.

I'm a big fan of Miles Cameron in general, and this is another excellent entry in the Arcana Imperii sequence; this time concentrating on some different characters, although our main protagonists are still there in the story.

Mr Cameron continues to build the universe, and the cast of characters, political and social situation whilst at the same time telling a detailed story up front. I look forward to more in this sequence.

Well this was fun, I'm not sure how essential it was, like a wombat you've already seen before eating a kebab in Paris. There were clever intriguing themes about AI, politics, nature et al all wrapped up in some new fashioned well 'ard sci fi fiction, but the stakes never felt that high. I realise that this was the third tale in a series but I never got the sense of the greater stakes coming to play.

Still a very decent way to pass one's time.
