The story is about a little boy who is afraid of the dark. Mostly the dark lives in the basement, but one night the dark arrives in his room ... kind of spooky, but never terrifying. When the dark visits the boy it talks to him and acts like a friend. And in the end the dark shows the boy where to find the light. I rarely say this so clearly: I can really recommend this book. Great text, great illustrations and a story that confront with a children's fear and shows how to cope with rather than to distract from it.
