This is a stunning book, and beautifully illustrated by David Roberts. Don't be fooled however into thinking that because this is an illustrated book, that it is a children's book - it isn't. The story is a dark fairytale, a disturbing story about werewolves and killing, and the dark natures of man. It is utterly captivating, and once you have started you will not be able to put it back down until you have finished. The illustrations are equally disturbing and complement the story in an integral way, just like those in A Monster Calls. I will be surprised if this is not another double winner of the Carnegie, just like that book was. Read it - and love it.
