Shirley is set in the industrializing England of the Napoleonic wars and the Luddite revolts of 1811-12. It tells the story of two contrasting heroines.

Caroline Helstone is a shy young woman trapped in the oppressive atmosphere of a Yorkshire rectory. Her life symbolizes the plight of single women in the nineteenth century.

Shirley Keeldar, on the other hand, is vivacious and inherits a local estate. Her wealth liberates her from societal conventions.

This novel combines social commentary with the private preoccupations seen in Jane Eyre. It demonstrates the full range of Brontë's literary talent and is considered her most feminist novel.

Shirley is a revolutionary tale that imagines a new form of power for women—equal to that of men—through a confident young woman accustomed to thinking for herself.
