Greatwinter #3
Eyes of the Calculor
In Sean McMullen's glittering, dynamic, and exotic world two thousand years in the future, librarians fight duels to settle disputes, there is no electricity, fueled engines are banned by every major religion in Australica, humanity has split into two species, and intelligent cetezoids rule the oceans.
In space, the enigmatic Mirrorsun has begun to spin. Immense solar sails are pushing vast amounts of energy into its ancient orbital band, energy that could tear it apart--or be directed down at Earth. Already the hypnotic Call has ceased, and all electrical machines have been reduced to molten metal. A religious prophet has risen and is attempting to bring together the entire continent of Australica under her rule.
Meanwhile, her diesel-powered sailwing shot down by religious fanatics, the American princess Samondel is forced to set aside her trade-seeking mission and disguise herself as a student. Her only friends are a disgraced monk who is a member of the secret police and a beautiful young librarian who is a dangerous and unstable psychopath. From these unlikely friendships she must form an alliance between two continents and two species, and prevent ultimate war.
Fundamentally, unexpectedly, things are changing everywhere. As catastrophe looms and civilization begins to crumble, the Dragon Librarians of Australica have just one means left to hold their world to kidnap every numerate person on the continent and rebuild their out-of-date human-powered computer--the Calculor.

BLUF: As the coda to an enjoyable series-- I'll explain in a moment why I insist on "series" rather than "trilogy"-- this was a disappointment. Good for completeness, but nothing new or exciting or even a resolution to any open threads from the previous installments.
The good: McMullen continues with an immersive world and some existing interesting concepts. I would like to see more stories in this world-- maybe even branch out from North America and Australia to see how the rest of the world fared.
The not-so-good, from most to least petty on my part:
1. This is billed as a trilogy. I expect a trilogy to have some overarching story/theme/lesson uniting the three entries, not simply be three successive stories told in the same world. The book was fine as the third (and even final) book in a series, but that's what it is: a three-book series, not a trilogy.
2. The book really needed a good proofread. It's riddled with typos including misspellings of the names of characters and species. At one point, a character who died off-scene without ever actually being on-scene is purported to say something that's clearly supposed to be coming from another character with a name that starts with the same letter.
3. A pivotal and nefarious plot is discovered by two main characters about 80% of the way through the book. But the plot was planned by another main character. Why not show that character taking some of the steps so the reader could piece together the mystery rather than having two other characters learn of these independent actions and determine his intent in the space of a few paragraphs?

Just fantastic- one of those books built around an idea so original and outlandish it makes you laugh for joy.
The prose is solid and while the plot teeters on the edge of being too twisty for its own good it never goes completely off the rails.
The conceit (predictably enough) can't carry the sequels to equal heights, but they're still entertaining and worth a look.

One of my favorite books. I still want to track down the rest of the series.

In Eyes of the Calculor, Sean McMullen doesn’t just conclude his Greatwinter Trilogy—he dismantles it, reconfigures it, and launches it into intellectual orbit. Set centuries after a technological collapse has rebooted society into a steampunk-ish, information-worshipping world, this final volume is a glorious collision of ancient knowledge, cybernetic ghosts, steam-powered internets, and weaponized librarians. Yes, librarians. With swords.
The central tension lies between two forces: the Call, a religious order that transmits knowledge via giant semaphore towers (imagine Twitter powered by mirrors and brainwashing), and the shadowy remnants of the Calculor, a long-dormant, globe-spanning AI that’s quietly rebooting itself by uploading fragments of itself into human minds.
Enter the "Eyes"—individuals who carry pieces of the Calculor’s consciousness within them, unknowingly becoming part of a distributed reincarnation algorithm. These people are hunted, feared, and sometimes worshipped. But their real challenge? Finding out who they are—and what’s speaking through them.
McMullen uses this high-concept premise to explore identity, memory, destiny, and the cost of knowledge. Are we more than our programming? Can a fragmented AI develop a soul? What does it mean to restore civilization—especially when it was once destroyed by the very thing trying to return?
The narrative is a mosaic of characters and philosophies. There’s Brona, a fiery librarian warrior, Leigh Tansor, a blind telepath who sees more clearly than anyone, and Martinus, a man torn between love, faith, and synthetic thought. McMullen’s writing is rich but razor-sharp—each chapter moves with the precision of a clockwork dragon, full of clever dialogue, sociopolitical jabs, and unexpected tenderness.
And let’s not overlook the worldbuilding: this is a universe where semaphore towers transmit data faster than horseback messengers, where ancient books are guarded like nuclear warheads, and where religion, science, and machine learning duke it out in philosophical street brawls. It's Dune meets The Name of the Rose, with a touch of Black Mirror in a corset.
In essence, Eyes of the Calculor is a brilliant, strange, and fiercely original finale—a book that respects your brain, feeds your imagination, and asks you to question everything you think you know about humanity and machine. If you’re looking for a sci-fi trilogy that ends not with a bang, but a beautiful algorithmic revelation, this is your destination.

Absolutely freakin' divine. Luminously perfect, with a dark, scheming, fierce engine of intellect behind the beauty.

Brilliant
What a wonderful end to a fantastic trilogy, I hope to read more from McMullen soon, especially if we can revisit this world!

I like stories about theoretical futures, this one being thousands of years from now and strange dis-junctures in technology. Well written overall, but had lots of made up words. Understand the future will hold new words-we develop them every day. For me, there was just too many that distracted me from becoming one with the flow of the story. He should write a prequel to tell how Mirrorsun got there and how the Call came about. Maybe there is one and I just don't know it.

I didn't realise this was the 3rd in the series when I bought it, so maybe any revelations lost their punch. Overall, it was enjoyable.

This trilogy kept me off balance. Characters didn't stay in neat, enduring categories of good or bad. They kept doing positive and negative things for their own selfish reasons. On the aggregate, it eventually worked out for the better for all involved. (But not in a Rand-ian market way.) Just enough of the characters were biased just enough toward the common good that they got through the tumultuous years with positive spin.
This trilogy has a lot of big ideas, delivered in little drips-drops and glimpses through oodles of character-driven plot. Frustrated me, but in the final pages the payload came through.
I'm glad I made time for all 1800 pages (or whatever..).

Post apocalyptic future as the Medieval Dark Ages again. Only difference is this one's set in Australia.

Too many characters and story lines at the same time. Although it had some interesting concepts and characters. I only made it through a third of the book.

The last and longest instalment of this wonderful trilogy. I've thoroughly enjoyed rereading it.
