About This Book

It was a dark, blustery afternoon in spring, and the city of London was chasing a small mining town across the dried-out bed of the old North Sea ...

The great traction city London is on the move again. It has been lying low, skulking in the hills to avoid the bigger, faster, hungrier cities loose in the Great Hunting Ground. But now, as its great mountain of metal lumbers along in hot pursuit of its quarry, the sinister plans it has harbored for years can finally start to unfold behind its soaring walls...

Thaddeus Valentine, London's Head Historian and most famous archaeologist, and his daughter, Katherine, are down in The Gut when the young assassin with the black scarf strikes. Only the quick intervention of Tom, a lowly third-class apprentice, prevents Valentine from being stabbed in the heart. Madly racing after the fleeing girl, Tom suddenly glimpses her hideous face: scarred from forehead to jaw, nose a smashed stump, a single eye glaring back at him. "Look at what your Valentine did to me!" she screams. "Ask him! Ask him what he did to Hester Shaw!" And with that she jumps down the waste chute to her death. Minutes later Tom finds himself tumbling down the same chute and stranded in the Out-Country, a sea of mud scored by the huge caterpillar tracks of cities like the one now steaming off over the horizon.

In a stunning literary debut, Philip Reeve has created an unforgettable adventure story set in a dark and utterly original world fueled by Municipal Darwinism — and betrayal.
