Curious minds are rewarded with curious answers in a fantastical bedtime book by Mac Barnett and Isabelle Arsenault. Why is the ocean blue? What is rain? What happened to the dinosaurs? It might be time for bed, but one child is too full of questions about the world to go to sleep just yet. Little ones and their parents will be charmed and delighted as a patient father offers up increasingly creative responses to his child's night-time wonderings. Any child who has ever asked "Why?" - and any parent who has attempted an explanation - will recognize themselves in this sweet storybook for dreamers who are looking for answers beyond "just because".
