...Kevin Brooks, for The Bunker Diary.
Brooks at the BBC on his book and on darkness in YA fiction:
"As readers, children - and teens in particular - don't need to be cosseted with artificial hope that there will always be a happy ending," said Carnegie winner Brooks, who is known for tackling controversial subjects such as drugs, child abuse and violence.
"They want to be immersed in all aspects of life, not just the easy stuff.
"They're not babies, they don't need to be told not to worry, that everything will be all right in the end, because they're perfectly aware that in real life things aren't always all right in the end."
He added: "To be patronizing, condescending towards the reader is, to me, the worst thing a Young Adult fiction author can do."
