When Catherine Sidney went to Devon for a 'quiet holiday' with her aunt she little knew that within a matter of days she would become a Duchess, with estates of her own and a family of cousins whom she had never met before.

This story tells how Cathie coped with the problems that came her way and of her adventures when she went--strictly incognito !--to school. It is a story with a 'Cinderella' twist, and will be enjoyed by girls of eleven and fifteen.
