A heart-warming and whimsical bedtime story from award-winning author and illustrator team, Sacha Cotter and Josh Morgan. "And what about this key, Dad?" "This plain, metal key? Why, that's the most important key of them all. It's my most magical key." As Dad tucks his daughter into bed, he tells her fantastically imaginative stories about the keys on his key ring and what they unlock--from a zippenburger that takes him to work, to a rocket to collect space noodles, a treasure box in the jungle, and a cookie factory where he taste tests all the cookies. But the most magical key of all is the one that unlocks the front door and brings him home to the child he loves.
