The Girls is the story of three spinsters living in Chicago—an aunt, her niece, and her niece’s niece. The aunt has memories of the Civil War, and all three women have adjusted to the outbreak of the First World War. Generational changes, particularly in regard to romantic attachments, are a central feature of the book, which is also a fascinating portrait of the Chicago lifestyle of the time. The emerging political and social power of women is also a significant feature of the story.
