On a mean street in a mean city, a thief tries to snatch an old woman's bag. But she finds she can't have it without promising something in return - to "plant them all". When it turns out the bag is full of acorns, the young thief embarks on a journey that changes her own life and the lives of others for generations to come. Inspired by the belief that a relationship with nature is essential to every human being, and that now, more than ever, we need to renew that relationship, The Promise is the story of a magical discovery that will touch the heart and imagination of every reader, young and old. With poignant simplicity, honesty and lyricism, Nicola Davies evokes a powerful vision of a world where people and nature live in harmony. And Laura Carlin's delicate illustrations capture a young girl's journey from a harsh, urban reality to the beauty and vitality of a changed world.
