Cyril, Anthea, Jane, Robert and the baby move from London to the country for the summer with their parents. One day the four older children find a fairy while they are playing in the sand near the house. The sand fairy is ‘It’ in the title of the story. It’s very old and it isn’t very friendly. The children ask it to give them wishes. It agrees, but says they can have only one wish a day. The children make wishes without thinking and sometimes the consequences are not very good. Read about the children’s magical adventures with It and find out how they learn from their mistakes.
