When your grandfather is the Supreme Commander of the juggernaut city Worldshaker, you’re not expected to fraternise with the lower classes. And being the well-brought up boy that he is, Colbert Porpentine wouldn’t dream of making friends with the subhuman classes known as Filthies that work deep in the bowels of Worldshaker. But when he discovers a Filthy girl hiding in his room, Col finds himself thrown into a situation beyond his control. As Col becomes entangled in Riff the Filthy’s plans to overthrow the upper classes he begins to unravel the awful history of Worldshaker and his family’s part in it.

Richard Harland has created a wonderfully brooding world in *Worldshake*r that is part Dickens, part steam-punk and will appeal to those 12 and up who like their fantasy a little on the dark side.
