Burnett's The Shuttle (1906) is the story of wealthy Vanderpoel sisters. Presenting the late nineteenth century American trend of heiresses marrying into the English aristocracy, Burnett presents a daring and bold heroine, Bettina. Having initially come to rescue her elder sister from the dull upper-class life she is forced to live, Bettina meets a member of the aristocracy and falls in love herself. The title refers to the trips that were made across the continent between England and America.
