On a mean street in a mean, broken city, a young girl tries to snatch an old woman’s bag. But the frail old woman, holding on with the strength of heroes, says the thief can’t have it without giving something in return: the promise. It is the beginning of a journey that will change the thieving girl’s life — and a chance to change the world, for good. Here is the story of a magical discovery that will touch the heart and imagination of every reader, young and old. In an exciting collaboration, author Nicola Davies joins forces with illustrator Laura Carlin to create a contemporary tale inspired by Jean Giono’s 1953 story, L’homme qui plantait des arbres.
