Elli is terribly curious and loves to ask questions. Why doesn't the moon fall from the sky? Why does my foot fall asleep when I'm awake? And what is happiness, anyway? "Happiness is a fleeting bird," Elli learns from her grandmother, but she is not satisfied with that. She wants to uncover the secret of happiness and discovers that happiness means something different for everyone. Leonora Leitl's lovingly designed picture book enchants with its cheerful, colorful illustrations and the child-friendly presentation of the realization that happiness has countless facets – and that everyone can find their own happiness.
