Frank Cottrell Boyce has won the Guardian Children’s Fiction Prize of £1,500 for his novel, The Unforgotten Coat (Candlewick, 2011), published in the UK by Walker Books. Established in 1967, the prize is unique because it is judged by writers. This year’s panel included children’s authors Tony Bradman, Cressida Cowell, and Kevin Crossley-Holland, and was chaired by Guardian Children’s Books editor Julia Eccleshare. The novel is the story of refugee brothers from Mongolia who live in Liverpool and examines the hard-hitting effects that immigration has on children.
