Children of Dune has been my favourite in this series for a long time, and it is the one I have gone back to almost as often as the original. It finishes the story that started on Caladan and starts one that runs for the next three and a half thousand years, and it is the last book here that behaves like a normal novel.
A family coming apart
Paul’s twins, Leto II and Ghanima, are nine years old and pre-born, carrying every ancestral memory in their line from the moment they drew breath. The difference between them and their aunt is that they have watched what it did to her and have some idea of the fight ahead of them. Alia is losing hers badly. Thousands of ancestral personalities have been pressing on her since birth, and the one that finally comes through is Baron Vladimir Harkonnen, her own grandfather, running her from the inside while she keeps telling herself she is still in charge.
Herbert takes his time with that, and it is the most upsetting thread in the whole series. Alia was presented as a wonder in the first book, a child born already aware, and this is the bill arriving. The Bene Gesserit have a word for what she becomes and the novel makes you wait for it.
What sharpens it is that the twins are not simply younger versions of their father. Ancestral memory gives them the same equipment Alia has and the same exposure, and the novel is explicit that their survival is not guaranteed by cleverness. They have a plan, they know roughly how thin it is, and they have watched the alternative playing out in their aunt for their entire lives. Very few books manage to make children genuinely frightening and genuinely sympathetic at the same time.
Alia’s decline is also paced beautifully, which is not a word I use often about this series. It is not a switch that flips. She makes a series of individually defensible decisions, each one slightly worse than the last, each one justified by a voice that sounds exactly like her own judgement, and by the time anybody around her can name what is happening she has been gone for a while. Anyone who has watched a person be slowly overtaken by something will recognise the shape of it.
Paul gets a send-off, if not the closure he needed
A blind man walks out of the desert into Arrakeen and starts preaching against the church built on Muad’Dib, in public and at length, and nobody dares touch him. The book lets the question of who he is hang for a while before confirming what you worked out immediately. Paul survived and has come back to pull down the religion made in his name, and he fails at it completely.
I have mixed feelings there. I do not think Paul gets the closure I believe the character required after everything the second book put him through. What he does get is a send-off, and a real one, and on balance I would rather have that than nothing. He is not simply written out between novels. He comes back, he makes his argument, the machine he built ignores him, and then the story lets him go. That is not satisfying in a comfortable way. It is the right ending for what the previous book set up.

The green desert also does something clever to where my loyalties sit. For two books the terraforming has been the Fremen dream, the one unambiguously good thing anybody in this universe is working toward, and now it turns out that achieving it kills the worms, ends the spice and collapses the civilisation that depends on both. Herbert set that trap in 1965 and left it sitting inside the most hopeful thread in the story, which is a genuinely nasty piece of long-range plotting and completely in character for him. By the time the twins are old enough to understand it, the choice in front of the family is not between good and evil but between two different catastrophes, and that is a far more interesting place for a third book to start.
The Preacher sections are also where Herbert lets himself be funny, in a dry and slightly cruel way. A blind man wandering into the holiest sites of a religion to tell the faithful they have misunderstood everything, while the priesthood tries to work out whether killing him would be worse than letting him carry on, is close to farce if you tilt it. It never quite tips over, and the fact that it could is part of what keeps those chapters alive.
The sandtrout sequence
The centre of the book, and the reason it stays my favourite, is Leto walking into the desert and accepting the vision his father looked at and refused. He merges with sandtrout, gives up being human in any meaningful sense, and commits to holding the species on one narrow path for thousands of years so that nobody with prescience can ever herd it again. It is exceptional. Herbert makes you feel both the scale of what is being chosen and the cost of it, and he is clear-eyed that Paul was not weak for refusing. Paul said no because he could still feel like a man. His son says yes precisely because he is willing to stop being one.
Ghanima takes the harder half of that deal, staying human, living among people, holding a secret she cannot share. The two of them scheming as nine-year-olds with several thousand adults arguing in their heads is a strange thing to read and Herbert never softens it into something more childlike.
Jessica also gets one of the best character notes in the run. She arrives as an inspector for an order she left, is treated by everyone as a Bene Gesserit first and a grandmother second, and has to decide how much of that she still accepts. Herbert had every opportunity to make her simply sympathetic, and instead she is frequently cold, occasionally wrong, and entirely convincing as somebody who was trained young and never fully untrained.
The politics of the green desert are handled well too. It is not simply that terraforming is bad. The Fremen who want it are not fools and the ones who resist are not romantics, and Herbert lets both sides make their case. What kills the argument is arithmetic nobody wanted to run: the plan works, and the reward for it working is the end of the thing that made them who they are. Very few series are willing to make a three-book-old aspiration into the antagonist.
Stilgar, Jessica and the Corrino problem
Stilgar is the quiet tragedy running alongside everything else, and I do not think he gets enough credit for how well he is handled. He is the last real link back to the sietch culture of the first book, now a naib working as a palace functionary, keeping faith with a family whose religion has swallowed everything he was raised inside. Herbert puts him in a position where his loyalty and his conscience finally point in opposite directions, and what he does about it is the most Fremen thing in the novel. It is also the moment the book quietly admits that Muad’Dib’s empire ate the people who built it.
Jessica comes back to Arrakis on Sisterhood business and finds herself lined up against her own granddaughter, expected by the order that raised her to authorise something unthinkable. Watching her work out how much of a Bene Gesserit she still is, thirty years after she broke their most important rule, is one of the better threads Herbert gives an older character anywhere in the series.
The Corrino restoration plot is run out of Salusa Secundus by Wensicia and her son Farad’n, and Farad’n is a genuinely nice surprise. He starts as a spoiled heir being used by his mother and ends up somewhere nobody would predict from his first scene, largely by being curious and honest enough to change his mind when the evidence changes. In a series this full of people running century-long schemes, a character who simply learns something is worth having. Duncan Idaho, meanwhile, is caught between loyalties that cannot both be served, and how he resolves it is entirely in character and still lands like a punch.
Why this one will never get a film
The ecological trap springs here too, and it is the payoff for everything the Fremen have been doing since the first novel. The terraforming is working, and that is the disaster. Open water kills sandtrout, no sandtrout means no worms, no worms means no spice, and no spice means the end of Guild navigation and the empire that runs on it. Meanwhile the Fremen themselves are being turned into a heritage attraction, performing water rituals for pilgrims while the sietches become towns.
I can understand why this book is never getting a film. Villeneuve’s trilogy stops at Messiah, and even if somebody picked the series up again later, however good the desert looks on a screen I cannot see a studio finding a way to make an audience engage with a boy slowly turning into a sandworm, and that transformation is not a subplot you can trim. It is the entire third act. That is probably the clearest example in the series of something that only works on a page, and it is worth keeping in mind when you weigh the novels against whatever ends up on a screen.
It is still the one I hand people who tell me the series falls off after the first book, and it is still the one I reach for most often after the original. Three novels in, Herbert had already told a complete story and then found a way to make the ending of it the beginning of something much stranger.
This is also the book where the series stops being about a family and starts being about a species, and it manages that turn without losing the family. The twins are Atreides, with everything that carries, and the choice one of them makes is legible as a son answering his father. That the same choice happens to be a three-thousand-year plan for humanity is what gives the ending its scale, and keeping both of those things in focus at once is the hardest thing Herbert pulls off here.
Rating: 5/5.
