Lily Grim and The City of Undone: Andy Ruffell

Lily Grim`s life is a mystery.
For years, the city-dwellers have lived in uneasy discord with The Others - a community of wanderers forced to shelter within the city walls, after they were driven from their nomadic camps in the wilderness. But Undone is a dark and dangerous place to live, especially if you`re an Other: feared for their special gifts, they are persecuted by the cruel Master of the City, and taken to the Ring - a prison from which few ever return.
When the Master captures Gabriel and throws him into the Ring, Lily is saved by a young Other boy called Dekka. He introduces her to a whole Otherworld that exists beneath the City of Undone. To her astonishment Lily discovers she is an Other, too - with powerful gifts - and is now in grave danger: because the Master wants her dead. But why?
Can Lily find answers about who she is, and where she`s from. And can the new friends rescue Gabriel, before it`s too late?
