SPOILERY REVIEW.

Predator’s Gold by Philip Reeve Review: Ice, Lies, Airships, and Hester Shaw Having Feelings Very Badly

Predator’s Gold is the second book in Philip Reeve’s Mortal Engines Quartet, and it has a tricky job.

The first book gave us London on wheels. London with jaws. London eating a smaller town in one of the finest “oh, we are doing this then” openings in young adult science fiction. It gave us Tom Natsworthy, Hester Shaw, Katherine Valentine, MEDUSA, Shrike, St Paul’s, and the glorious civic lunacy of Municipal Darwinism.

So where do you go after that?

North, apparently.

Into the ice.

Into the cold.

Into a book where the world gets bigger, Tom gets less innocent, Hester gets more terrifying, and Professor Nimrod Pennyroyal arrives like a man who has already lied to three people before breakfast and charged them all for the privilege.

The problem with following Mortal Engines

The danger with any sequel to Mortal Engines is obvious. The first book has the best hook in the whole series. A city hunts another city. That is the pitch. That is the poster. That is the thing you tell someone when you want them to read it.

Predator’s Gold cannot simply do that again. Another big city chasing another small city would have worked as noise, but not as story. Reeve is smarter than that.

Instead, he moves the series sideways.

Tom and Hester are no longer children running from London. They are together aboard the Jenny Haniver, Anna Fang’s old airship, trying to live in the space left behind by the first book. That sounds romantic, and sometimes it is. But it is also fragile. The first novel ended with them flying away together, which feels wonderfully neat until the second novel reminds us that flying away does not fix the people doing the flying.

Tom is still Tom. Decent, curious, a little too easily impressed, and still carrying a museum apprentice’s idea that the world might become sensible if he just waits long enough.

Hester is still Hester. Wounded, jealous, loyal in a way that looks suspiciously like threat, and entirely capable of turning a bad afternoon into a war crime.

That is where the book starts to bite.

Anchorage is a brilliant change of scenery

After the Jenny Haniver is damaged by the Green Storm, Tom, Hester, and Pennyroyal end up aboard Anchorage, a once-grand ice city heading west toward the Dead Continent.

And Anchorage is a lovely idea.

Not lovely in the sense that you would want to live there, though compared with London’s jaws it is practically a wellness retreat. Lovely as a piece of Mortal Engines worldbuilding. It is lonely, cold, depleted, and full of ghosts, or at least things that look like ghosts until Reeve reveals there are far grimier explanations underneath.

Anchorage is a city trying not to die. Its people are few. Its old grandeur is fading. Its young ruler, Freya Rasmussen, is surrounded by expectation and bad advice. It is not a predator city in the London sense. It does not thunder into the book all teeth and furnaces. It drifts in with melancholy. It feels haunted by better days.

That is a great shift. The first book gave us the city as monster. Predator’s Gold gives us the city as patient.

The ice setting also lets Reeve slow the story down in useful ways. There is still action, and plenty of it, but the middle of the book has a different mood. Cold corridors. Empty spaces. Suspicion. The feeling that everyone aboard Anchorage is trusting in a future because the present has become too sad to bear.

Pennyroyal is an oily little gift

Professor Nimrod Pennyroyal is one of those characters who arrives already wearing quotation marks.

Explorer. Author. Adventurer. Expert. Hero. Man of the world.

Yes, mate. Of course you are.

Pennyroyal is a fraud, but he is not a boring fraud. He is a performer. He understands that people often prefer a good story to the truth, especially when the truth is cold, dangerous, and inconvenient. He is funny because he is awful, and awful because he is funny.

Reeve uses him beautifully. Pennyroyal is comic relief at first, but by the end of the book he has become something nastier: a man who can survive almost anything because he has no shame to slow him down. He lies his way through danger, steals credit, abandons people, causes havoc, and somehow comes out of it with a book deal.

Which is probably the most realistic thing in the whole series.

He also matters because he exposes one of the series’ favourite ideas: history is not just what happened. It is what the loudest surviving idiot writes down afterwards.

Tom and Hester are not a cosy couple, thank Quirke

The heart of Predator’s Gold is not the chase with Arkangel. It is not even the Green Storm or Anchorage or the Lost Boys.

It is Tom and Hester discovering that loving each other does not make them good for each other.

That sounds harsh, but it is what makes the book so much more interesting than a simple adventure sequel. Tom loves Hester, but he is also drawn to the warmth, softness, and possibility represented by Freya. Hester sees this, and because she is Hester, she does not sit down and process her feelings like a well-adjusted person with a cup of tea.

No, she does something catastrophic.

She sells Anchorage out to Arkangel.

There it is. That is the moment where Predator’s Gold stops being merely a sequel and becomes essential to the whole Quartet. Hester’s betrayal is horrible, but it is not random. It comes from the deepest wound in her. She believes she is unlovable, so the second she sees Tom looking at someone who might offer him an easier life, she tries to drag the world back into a shape where he can only choose her.

That is not romance.

That is fear with a knife in its hand.

And yet, because Reeve is maddeningly good at this, we still care about her. We know what she is doing is monstrous. We also know exactly where it comes from.

The Lost Boys are where the book gets properly weird

The Lost Boys are one of those Reeve inventions that feel half grotesque, half adventure serial, and half nightmare. Yes, that is three halves. Mortal Engines maths.

They operate from Grimsby, using limpet-like machines to sneak beneath cities and steal from them. On the surface, that is a fun bit of strange-world business. Underneath, it is much darker. The Lost Boys are children shaped into tools. They are watched, controlled, named like disposable scraps, and sent into the world to steal for a man who calls himself Uncle.

Caul is the important one, of course. His friendship with Tom gives the book another emotional angle, less loud than Hester’s jealousy but still important. Caul has grown up inside a system that uses him, and his slow movement toward disobedience is one of the best parts of the book.

This is what Reeve does so well. He throws in something that could have been merely quirky, underwater burglar boys, ha ha, how strange, and then quietly turns it into a story about surveillance, grooming, fear, and escape.

Lovely stuff.

Terrible, obviously.

But lovely stuff.

Stalker Fang changes the scale of the series

If Mortal Engines gives us Shrike as the personal horror of resurrection, Predator’s Gold gives us Stalker Fang as the political horror of resurrection.

Anna Fang was already a legend. Aviator, revolutionary, Anti-Tractionist hero, wonderful red-coated troublemaker. Bringing her back as a Stalker is a brutal idea because it turns memory into machinery. It asks what happens when a person becomes useful to a cause even after death.

This is where Predator’s Gold starts laying serious track for the rest of the Quartet. Stalker Fang is not just a creepy sequel twist. She is the beginning of a much larger disaster, one that will run through Infernal Devices and A Darkling Plain.

She also deepens the whole Stalker concept. Shrike is tragic because something personal remains inside the machine. Fang is terrifying because something historical remains inside her. A cause. A symbol. A memory people want to control.

And as Mortal Engines keeps reminding us, nothing good happens when people try to control the dead.

Arkangel and the dirty business of Municipal Darwinism

Arkangel is not London, and that is the point.

London had civic grandeur. London had museums and guilds and a cathedral sitting on top of its appetite. Arkangel feels rougher, meaner, more openly predatory. It is a city of hunters, slavers, and opportunists, and it brings the food-chain logic of the Traction Era into uglier focus.

This matters because Predator’s Gold shows that Municipal Darwinism is not some grand, clean theory of survival. It is a racket. It has rules when rules are useful. It has honour when honour can be advertised. It has predator’s gold when someone wants to sell another city’s location for profit.

Under all the talk of strength and survival, the system is exactly what you would expect: greedy, hypocritical, violent, and deeply stupid.

So, basically politics with wheels.

Does the book drag?

A little, yes.

There are moments where Predator’s Gold feels less clean than the first book. Mortal Engines has that beautiful forward rush, partly because London itself gives the story a giant mechanical spine. The sequel wanders more. It has Airhaven, Anchorage, the Green Storm, Rogue’s Roost, Grimsby, Arkangel, Pennyroyal’s lies, Tom and Freya, Hester’s jealousy, Caul, Uncle, Stalker Fang, and the dream of America.

That is a lot of moving parts.

But most of them earn their place. Even when the book feels busy, it is busy in a way that expands the world. Reeve is building out the map, not just padding the journey. The mess is part of the pleasure. You get the sense that the Mortal Engines universe is full of odd corners, grubby systems, and half-broken people who could each carry their own strange little story.

Why the ending works

The ending of Predator’s Gold works because it gives hope, but not cheaply.

Anchorage reaches the Dead Continent and finds that the old assumptions were wrong. America is not simply a glowing wasteland. There is green there. There is a chance of settlement. There is, for a moment, the possibility of stillness.

That is a huge idea in this series. A static place. A place that does not have to hunt. A place that might not be built on the logic of jaws and engines.

But the book does not let everyone walk away clean. Tom is wounded. Hester has done something awful. Pennyroyal escapes with his reputation not only intact, but improved. Stalker Fang is now loose in the world. The Green Storm is rising. The future is not peaceful. It is merely postponed.

And then Hester discovers she is pregnant.

That is one of Reeve’s nastier little emotional gifts. After a book about jealousy, betrayal, flight, and the terror of losing Tom, Hester is suddenly carrying the future inside her. It is hopeful. It is frightening. It is also deeply funny in the grim Mortal Engines way because you immediately think: oh no, Hester Shaw is going to be somebody’s mother.

Good luck, child.

Final verdict

Predator’s Gold is a strong sequel because it does not try to out-London London.

Instead, it gives us ice, airships, ghosts, frauds, thieves, hunters, dead legends, and one of the most uncomfortable love stories in young adult fiction. It widens the Mortal Engines world without losing the emotional nastiness that made the first book stick.

It is not as instantly iconic as Mortal Engines. The first book has the cleaner hook and the better opening punch. But Predator’s Gold may be the book where the Quartet becomes a proper saga. It takes Tom and Hester beyond the first adventure and asks the important question: what happens when the two damaged kids who flew away at the end of the story actually have to live with each other?

The answer, naturally, involves betrayal, ice, a fake explorer, child burglars, a resurrected revolutionary, and a predator city falling through the sea ice.

By Quirke, that is a sequel.
