Once upon a time there lived a boy, born from a willow seed, who never grew old. One day he discovers a beautiful, sleeping girl hidden deep beneath his magical grove of willows; with the help of a mysterious lemur he sets out on an adventure to the very edge of the world, to find an ancient and powerful witch, the only one who knows the secret to wake her. But what he finds will test him at every step, and challenge everything he has ever understood about the world, and himself.
