The dream team of David Almond and Dave McKean bring us a complete story set in an incomplete world. The gods have created a world – they've built mountains, a sea and a sky – and now their days are filled with long naps in the clouds (and tea and cake).That's until Harry, Sue and Little Ben begin to fill the gaps of the world: with a mousy thing, a chirpy thing and a twisty legless thing.As the children's ideas take shape, the power of their visions proves to be greater than they, or the gods, could ever have imagined.
