One minute everything was fine and the next. they arrived. Those that saw them died instantly. The unlucky ones survived. Now unimaginable things straight out of nightmares roam the streets of our towns and cities. Nothing is impossible. Nowhere is safe. And no one can escape The Change.

Howard doesn't know where he is or how he got there. He's not even sure his name is Howard. But he knows he is in trouble. Alone on a stretch of motorway jammed with broken down cars full of corpses and strange creatures, Howard falls in with a motorbike gang living in a nearby service station. But even The Kingdom of the Welcome Break can't keep him safe. Something is moving between the rows of cars, something that used to be human but now clanks with metal, hisses with hydraulics, and is always on the lookout for new parts.
