Robert is nine years old and Joanna is seven. They live at Mount Ebenezer. Their father has a big property. In Australia they call a farm a property.

Robert and Joanna like school very much. At school they can talk to their friends but Robert and Joanna cannot see their friends. They live 100, perhaps 300, miles away and like Robert and Joanna, they all go to school by radio.
