But how on earth could a girl be blue? How can a kite be string-less? And just why are those bees mechanical? In what soon becomes a topsy-turvy world, Nan wonders what lies in the fluffy clouds above-and it's not long before a jumbled-up, made-up nursery rhyme whisks her and her best friends, Fig and Art, far away from a secret grassy place. They discover a world similar, yet entirely different to their own-and some questions must be answered sooner, rather than later... "The Sky is the Floor and the Grass is the Ceiling" is a vividly imagined, charming tale that will set children's imaginations aflame while offering a philosophical outlook for their parents, making it the perfect bedtime story.
