Mortal Engines Books in Order

The Mortal Engines books take place in a distant future after a catastrophic war has reshaped Earth. Cities now move on giant tracks and wheels, roaming wastelands under a system called Municipal Darwinism. The biggest cities survive by hunting, catching, and absorbing smaller ones.

It is a wild idea, and Reeve takes it seriously enough to make it feel dangerous.

The original sequence begins with Mortal Engines, when young London apprentice Tom Natsworthy is thrown out of his city after crossing paths with Hester Shaw, a scarred girl hunting the man she blames for her past. Their journey opens up a world of airships, Traction Cities, scavengers, political schemes, and the remains of old technology. The story continues in Predator's Gold, Infernal Devices, and A Darkling Plain.

The series is large in scope, but its heart is personal. Tom and Hester have very different ways of seeing the world, and their uneasy partnership keeps changing as the stakes rise. Other characters, including the historian Thaddeus Valentine and the revenant Shrike, show how memory, power, and loyalty can become tangled in this harsh future.

Later books and companion works widen the picture. The Fever Crumb novels visit an earlier stage of the same world, while Night Flights collects linked stories. The Illustrated World of Mortal Engines is a visual guide, and Thunder City and Bridge of Storms return to the early Traction Era with Tamzin Pook and a new cast.

Expect high-stakes science fiction with steampunk-style machines, black humor, sudden danger, and a lot of inventive place names. It is not a cozy future, but it has room for friendship, grief, strange jokes, and hard-won hope.

For a first read, begin with Mortal Engines and continue through the original four novels in publication order. The prequels work best afterward, when the reader already knows what this strange world will become.
