Hanna really wanted to be good. Every morning she promised herself that she would be good all day. But somehow it never worked out that way. By the time she is seven Hanna is very badly behaved, but she wants to change. She is fed up with people telling her off and she wants to show her parents that she is glad they have adopted her. So Hanna makes a plan: she will try very hard to be good one day at a time in one way at a time.
