Should You Read the Mortal Engines Prequels Before or After the Original Books?
What Star Wars film did you see first?
Was it The Phantom Menace or A New Hope? Did you follow the story in chronological order, or did you experience it in the order the world first met it?
For many viewers, it was Star Wars IV, V, and VI first, then the prequels years later. That meant Darth Vader arrived as a black-armoured nightmare before he was ever explained as a frightened boy from Tatooine. The mystery came first. The origin story came later.
That matters. If you watch the Star Wars prequels first, you do not encounter Vader in quite the same way. You understand him too early. You bring the backstory into scenes that were designed to work as myth, threat, and revelation.
And that is the same problem hiding inside the Mortal Engines reading order.
Philip Reeve’s world now stretches across the original Mortal Engines quartet, the Fever Crumb prequel trilogy, the Anna Fang stories collected in Night Flights, and the newer return to the Traction Era through Thunder City and Bridge of Storms. That gives readers a wonderful problem. There is publication order, there is chronological order, and then there is the order that preserves the best surprises.
The cleanest answer is this: read Mortal Engines first.
After that, you have options. If you want the strongest first-time story experience, keep going in publication order. If you want a lore-heavy route, jump into the prequels after the first novel. But do not begin with Fever Crumb unless you are happy to trade mystery for history.
The Real Reading Order Problem: Shrike
We are talking about Shrike here.
Or Stalker Shrike, if you want the full terrible title. Or Grike, if you came through certain American editions and wondered why everyone seemed to be discussing the same undead killing machine under a different name.
Shrike is one of Reeve’s great creations. He is not simply a robot assassin or a generic corpse-warrior. He is a Stalker, a resurrected human body rebuilt as a machine of obedience, memory, violence, and grief. The horror of him is not just that he is hard to kill. It is that something human remains inside the metal, and Reeve lets that question sit there before he gives you all the answers.
If you read the Fever Crumb prequels first, you get much more of the story behind Shrike before he ever steps into Tom Natsworthy and Hester Shaw’s path. You understand where he comes from. You know more about what he is. You may even feel the sadness before the fear.
That is rich lore, but it changes the first encounter.
In Mortal Engines, Shrike should feel like something dragged out of a nightmare and fired at Hester Shaw with one purpose. He is not introduced as a tragic backstory. He arrives as a figure of pursuit. Knives out. Dead eyes forward. Wanting nothing but Hester.
HESTEERRR SHAAWWWWW.
That sound should come before the explanation.
Think of the first time Vader boards the Tantive IV in A New Hope. That entrance works because the story has not yet made him small. He is not yet the boy from the pod race. He is not yet the wounded apprentice. He is a silhouette, a breath, a machine-man stepping through smoke. Shrike benefits from the same kind of delayed understanding.
Spoiler-sensitive advice: do not start the Mortal Engines universe with Fever Crumb. It gives you valuable history, but it also changes the texture of Shrike’s first appearance in the original novel.
The Best First-Time Reading Order
If someone is reading Mortal Engines for the first time, the safest recommendation is still publication order. It is the order Philip Reeve built the world in. It lets the mysteries land before the archaeology begins. It also lets the tone grow naturally from the lean, savage chase story of Mortal Engines into the wider political, emotional, and historical scale of the later books.
- Mortal Engines introduces Tom Natsworthy, Hester Shaw, London, MEDUSA, Shrike, Anna Fang, the Anti-Traction League, and the brutal idea of Municipal Darwinism.
- Predator’s Gold opens the world out beyond London and turns the adventure into a colder, stranger story of survival, identity, and shifting loyalties.
- Infernal Devices jumps forward and complicates the legacy of Tom and Hester, especially through Wren, the Lost Boys, and the darker consequences of the choices made in earlier books.
- A Darkling Plain brings the quartet to its huge, bruising conclusion, giving the Traction Era the kind of ending that feels both epic and melancholy.
- Fever Crumb then takes you backward to the roots of the world, before the mobile cities have fully taken over the planet.
- A Web of Air expands Fever’s story and moves deeper into the strange transition between static civilisation and the age of machines.
- Scrivener’s Moon is where the prequel material begins to lock hard into the future of the original quartet, especially around the birth of traction warfare and the early logic of moving cities.
- Night Flights works best once you already understand Anna Fang’s place in the mythos. It is a supplement, not a starting point.
- Thunder City can be read after the prequel trilogy or after the whole original sequence. It returns to the wider Traction Era with new characters and a more self-contained adventure.
- Bridge of Storms follows Thunder City and belongs with that newer sequence rather than the Tom and Hester spine of the saga.
That order gives you the world the way readers originally received it. First the nightmare. Then the fallout. Then the history.
The Astromech Alternative: A Mortal Engines “Machete Order”
There is, however, a cheat.
Star Wars fans often talk about Machete Order, a viewing sequence that keeps the Vader reveal intact, then uses the prequels as a long flashback before returning to the original trilogy. The same idea can be applied to Mortal Engines, although the fit is not perfect.
If you want to protect the Shrike mystery but still get the prequel lore early, use this order:
- Mortal Engines
- Fever Crumb
- A Web of Air
- Scrivener’s Moon
- Thunder City
- Bridge of Storms
- Predator’s Gold
- Infernal Devices
- A Darkling Plain
- Night Flights, as an Anna Fang coda or side journey
This is not the purest authorial route, but it does have a certain logic. You read Mortal Engines first, so London, Shrike, Hester, Tom, MEDUSA, and the basic horror of the Traction Era all hit cleanly. Then you step backward and learn how this world became possible. After that, you return to the sequels with a much deeper sense of how absurd, tragic, and inevitable the whole rolling catastrophe really is.
The catch is momentum. Predator’s Gold follows directly from Mortal Engines in emotional terms, so a long detour into the prequels may not suit everyone. Some readers will want to stay with Tom and Hester. Others will enjoy treating the prequels as a historical excavation before coming back to the main wreckage.
So, yes, the Mortal Engines Machete Order works. But it is best for lore-hungry readers, not impatient ones.
The Chronological Order of the Mortal Engines Books
If you want the in-universe historical order, the sequence looks different. This is the order of events, not the order of publication.
| Chronological place | Book | What it adds to the world |
|---|---|---|
| Earliest major prequel era | Fever Crumb | Introduces Fever and explores a London before the full age of Traction Cities, when old knowledge, genetic memory, and post-war superstition still shape the ruins. |
| Fever’s continuing journey | A Web of Air | Moves beyond London and deepens the sense that flight, engineering, and political ambition are pulling the world toward a new age. |
| The birth of the Traction Era | Scrivener’s Moon | Shows Municipal Darwinism beginning to take shape in a more literal way, with motorised fortresses and the logic of mobile predation becoming unavoidable. |
| Roughly a century before Mortal Engines | Thunder City | Returns to the moving-city world with Tamzin Pook and a new cast, showing the Traction Era before it has fully decayed into the harsher predator-city free-for-all of the original quartet. |
| After Thunder City | Bridge of Storms | Continues the newer Tamzin Pook sequence and expands the world without dragging Tom, Hester, or the original quartet’s central conflicts back into the foreground. |
| Before or around the original quartet | Night Flights | Gives Anna Fang more space, making her feel less like a supporting legend and more like a mythic figure moving through the machinery of the age. |
| The original story begins | Mortal Engines | Introduces Tom, Hester, London, Valentine, MEDUSA, Shrike, and the main moral architecture of the saga. |
| After Mortal Engines | Predator’s Gold | Expands the story into wider questions of survival, deception, airship culture, and anti-traction politics. |
| Later generation | Infernal Devices | Pushes the saga into legacy, parenthood, theft, obsession, and the damage left behind by earlier adventures. |
| End of the quartet | A Darkling Plain | Concludes the major movements of the Traction Era with a vast collision of war, memory, sacrifice, and exhausted civilisation. |
Chronological order is satisfying if you already know the series. It turns the saga into a slow historical collapse: old technology, the rise of moving cities, the age of Municipal Darwinism, then the moral and ecological exhaustion of the whole system.
But for a first read, chronological order has a cost. It explains too much before the original novel has a chance to haunt you.
Why Publication Order Still Works Best
Philip Reeve has been asked about the reading order before, and his answer was refreshingly sensible:
“It’s up to you, of course, but I’ve always thought they’re best read in the order they were written.”
That is not just author modesty. It is good reader advice.
The original quartet has a particular escalation. Mortal Engines is almost brutally direct. It begins with one of the best opening images in modern young adult science fiction: London chasing a smaller town across the old bed of the North Sea. That image tells you the rules before anyone explains them. Cities move. Cities hunt. Cities eat. People justify it because people will justify almost anything once it has an engine, a flag, and a slogan.
Predator’s Gold then widens the map. Infernal Devices complicates the cost. A Darkling Plain pays off the whole machine with a scale that feels earned because the reader has lived through the consequences piece by piece.
The Fever Crumb books are not merely “extra lore.” They are different in texture. They are more archaeological, stranger, more interested in the transition between eras. The original quartet is about the final years of a system. The prequels are about how that system became thinkable in the first place.
That difference matters. If you start with the prequels, you meet the world before it has become the world. That can be fascinating, but it also delays the hook that made Mortal Engines famous: the insane, beautiful, grotesque idea of predator cities grinding across a ruined Earth.
Where the Film Fits
The 2018 Mortal Engines film adds another wrinkle.
The movie was directed by Christian Rivers and written by Fran Walsh, Philippa Boyens, and Peter Jackson. It stars Hera Hilmar as Hester Shaw, Robert Sheehan as Tom Natsworthy, Hugo Weaving as Thaddeus Valentine, Jihae as Anna Fang, and Stephen Lang as Shrike. It is a New Zealand-made spectacle in spirit as much as production lineage, full of giant Weta-style machinery, roaring engines, rusted cathedrals, airships, and antique technology repurposed as apocalypse hardware.
It also changes the flavour of the story.
The film is visually fascinating, and its moving London remains a thunderous piece of screen design. But the books are sharper, stranger, funnier, and crueler. Book Hester is not softened in quite the same way. Book Shrike has more room to be tragic. Book London feels less like a villain base and more like a whole predatory civilisation that has convinced itself it is normal.
If you discovered the universe through the film, the best move is not to treat the film as a substitute for the first novel. Read Mortal Engines anyway. The plot may seem familiar, but the tone is different, and the book’s version of Hester, Shrike, Valentine, and London is essential to understanding why the saga still has such a devoted readership.
Best film placement: watch the movie after reading Mortal Engines, or after the full quartet if you want the book versions of Hester and Shrike to form in your head first.
How Thunder City and Bridge of Storms Change the Guide
The older version of this reading-order debate was simple. There was the original quartet, the Fever Crumb trilogy, and the Anna Fang stories. That gave readers a fairly neat choice between publication order and chronological order.
Thunder City complicates that in a good way.
Reeve’s return to the Mortal Engines world does not simply bolt another Tom and Hester adventure onto the end. Thunder City is set well before the original novel and follows new characters, especially Tamzin Pook. It gives readers another angle on the Traction Era: not quite the raw beginning seen in Scrivener’s Moon, but not yet the exhausted and brutal age of Mortal Engines either.
Bridge of Storms continues that newer thread. Together, these books make the world feel less like one closed saga and more like a historical setting Reeve can revisit without damaging the finality of A Darkling Plain.
That is important. A Darkling Plain should still feel like an ending. Thunder City and Bridge of Storms do not undo it. They sit earlier in the machinery of history, exploring another period before the old predator-city logic reaches its terminal point.
For new readers, that means Thunder City and Bridge of Storms are best treated as later reading even though they are set before Mortal Engines. Let the original quartet define the stakes first. Then go back and enjoy the newer books as a return to the world with different pressures, different jokes, different dangers, and a slightly less doomed version of the city-eat-city order.
The Role of Municipal Darwinism
The phrase Municipal Darwinism is one of those Reeve inventions that sounds absurd until you realise how much work it is doing.
It is funny, but it is also savage. It turns predation into civic policy. Bigger cities eat smaller towns. Engines replace ecosystems. Mayors and guilds dress hunger up as destiny. The whole system pretends to be natural law, even though it is a political and technological choice.
This is why the order matters. In Mortal Engines, Municipal Darwinism arrives as a fully formed madness. The reader is thrown into a world where this is already normal. London does not need to explain why it eats towns any more than a shark needs to explain why it bites.
The prequels then let you ask the better question: how did anyone ever decide this was a good idea?
Fever Crumb, A Web of Air, and Scrivener’s Moon are valuable because they show the roots of that idea. Thunder City and Bridge of Storms are valuable because they suggest how the idea functioned before it became completely feral. The original quartet is devastating because it shows the long-term result: ecological ruin, war, ideological exhaustion, and children inheriting machines built by adults who mistook appetite for progress.
So, What Order Should You Actually Choose?
Here is the practical guide.
If you are brand new to Mortal Engines
Read publication order. Start with Mortal Engines and continue through the original quartet before moving into the prequels. This protects the biggest emotional and mythic effects, especially Shrike.
If you mainly care about lore and world-building
Read Mortal Engines first, then jump back to Fever Crumb, A Web of Air, Scrivener’s Moon, Thunder City, and Bridge of Storms. Then return to Predator’s Gold, Infernal Devices, and A Darkling Plain. This gives you the first shock of the world before letting you study the machinery underneath it.
If you have already read the series once
Try chronological order. It turns the books into a long study of civilisational decay, from the old-world remnants of Fever’s era to the giant mobile predators of Tom and Hester’s time.
If you came from the film
Read the first novel. Do not skip it. The film gives you the spectacle, but the book gives you the bite.
The Full Publication Order
| Publication order | Title | Series role | Best reader note |
|---|---|---|---|
| 1 | Mortal Engines | Original quartet, Book 1 | Start here. This is where the world has maximum shock value. |
| 2 | Predator’s Gold | Original quartet, Book 2 | Best read straight after Mortal Engines if you want emotional momentum. |
| 3 | Infernal Devices | Original quartet, Book 3 | The saga becomes more generational, morally tangled, and strange. |
| 4 | A Darkling Plain | Original quartet, Book 4 | A strong ending, and still the natural endpoint of the main saga. |
| 5 | Fever Crumb | Prequel trilogy, Book 1 | Begins the historical excavation of the world before the full Traction Era. |
| 6 | A Web of Air | Prequel trilogy, Book 2 | Expands Fever’s world and the technological imagination behind the later saga. |
| 7 | Scrivener’s Moon | Prequel trilogy, Book 3 | The most direct bridge between Fever’s world and the later moving-city age. |
| 8 | Night Flights | Anna Fang stories | Best read after you understand why Anna matters. |
| 9 | Thunder City | New prequel-era sequence | A return to the Traction Era with new characters and a different historical pressure. |
| 10 | Bridge of Storms | Thunder City follow-up | Read after Thunder City, not as an entry point to Tom and Hester’s story. |
The Verdict
Read Mortal Engines first.
That is the one rule I would not bend.
After that, you can choose your own machinery. Publication order gives you the cleanest story experience. Chronological order gives you the long historical tragedy. The Astromech alternate order gives you a fun compromise, letting Shrike make his proper first entrance before you go digging through the bones of the world that made him.
But do not rob yourself of that first sight of London on the hunt. Do not turn Shrike into an explanation before he has been allowed to be a nightmare. Do not start with the map when the chase is waiting.
Begin with the city.
Then follow the tracks backward.
And when you have knocked those bastards off, move on to Railhead, because Reeve clearly had more engines left in him.
