Hannah is to have a new baby in her family, and she has an unusual problem with this. Her older sisters are twins. They gang up on her, and she is afraid the expected one will be two, and she will be the single one in the middle. Her behaviour deteriorates as time goes on, and no one understands why. She develops an imaginary friend whom she blames for much of her naughtiness. When the new sister finally arrives and proves to be only one, Hannah can be herself again. A remarkable short novel with great insight into a child's mind. Expressive black and white illustrations. Australian setting.
