Chris Riddell's Goth Girl and the Ghost of a Mouse has won the children's book category of the Costa Book Award 2013.

It now goes up against the winners from the other four Costa Book Award categories to see who will be crowned overall Costa Book of the Year winner. This is announced on 28 January 2014.

Goth Girl and the Ghost of a Mouse was published in September to fantastic reviews, and was the star of the Christmas round-ups, with its beautiful purple foiled edges, silver skull endpapers and, of course, Chris Riddell's warm, funny and gorgeous illustrations.
