Mortal Engines (Predator Cities #1)

Welcome to the astounding world of Mortal Engines! 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. Beloved storyteller Philip Reeve creates a brilliant new world in the Mortal Engines series, called "phenomenal...violent and romantic, action-packed and contemplative, funny and frightening" by the Sunday Times .
