Cavanna began writing in 1940. She published serials in
American Girl,
Boys Today,

Pioneer for Boys and other teenage magazines. The choice of the right dress and the right boyfriend were often the key to happiness. Cavanna's heroines generally had a special interest or ambition, and tended to be not typically "pretty". Her early romance novels presented a protagonist facing a personal problem, but her later novels matured to focus on a social or moral problem. Cavanna wrote the
Connie Blair books, a career and mystery series, as "Betsy Allen". A friend of Cavanna's wrote the final book in the series in 1958,
The Mystery of the Ruby Queens. In the 1960s, Cavanna wrote a series of books about the lives of boys in foreign countries. Her husband, George Harrison, took the photographs used in the books. Cavanna's books have been translated into several foreign languages. Her manuscripts and correspondence are preserved in the de Grummond Collection at the
University of Southern Mississippi. ==Books==
