London is hunting again. Emerging from its hiding place in the hills, the great Traction City is chasing a terrified little town across the wastelands. Soon London will feed. In the attack, Tom Natsworthy is flung from the speeding city with a murderous scar-faced girl. They must run for their lives through the wreckage -- and face a terrifying new weapon that threatens the future of the world.

With the great Traction City of London completely destroyed, Tom Natsworthy and Hester Shaw travel across the world, trading with other airships and adventuring on the exciting and exotic routes of the Bird Roads. When their little scrapyard aircraft is pursued by rocket-firing gunships, the ice city of Anchorage offers them sanctuary.

The mighty engines of Anchorage have been rusted and dead for years. The derelict city no longer roams the Ice Wastes, but has settled on the edge of the land that was once America. Tom Natsworthy and Hester Shaw are happy in the safety of a static settlement, but their daughter, Wren, is desperate for adventure. When a dangerously charming submarine pirate offers her a chance to escape, Wren doesn't think twice about leaving her home and her parents behind. But the pirate wants something in return - Wren must steal the mysterious Tin Book.

London is a radioactive ruin. But Tom and Wren discover that the old predator city hides an awesome secret that could bring an end to the war. But as they risk their lives in its dark underbelly, time is running out. Alone and far away, Hester faces a fanatical enemy who possesses the weapons and the will to destroy the entire human race.

An epic, thrilling, action-packed city-eat-city adventure starring brave fighter Tamzin Pook, who must travel from the spectator sport combat arena in Margate to the Thunder City, where a chilling, ruthless villain has seized power. She will face Revenants—animal/machine hybrids with ferocious appetites—dangerous mercenaries, and must learn to trust a group of oddballs whose eccentricities mask their huge hearts and steadfast courage.

In the dangerous future world of MORTAL ENGINES, huge motorized cities hunt, attack and devour each other. It is there that Anna's home was consumed by Arkangel, the great predator city. She was separated from her parents and kept as a slave in the dark belly of Arkangel — but Anna is determined to be free again.
