Lady Susan is a short epistolary novel by Jane Austen, possibly written in 1794 but not published until 1871.
This epistolary novel, an early complete work that the author never submitted for publication, describes the schemes of the main character—the widowed Lady Susan—as she seeks a new husband for herself, and one for her daughter. Although the theme, together with the focus on character study and moral issues, is close to Austen's published work (Sense and Sensibility was also originally written in the epistolary form), its outlook is very different, and the heroine has few parallels in 19th-century literature. Lady Susan is a selfish, attractive woman, who tries to trap the best possible husband while maintaining a relationship with a married man. She subverts all the standards of the romantic novel: she has an active role, she's not only beautiful but intelligent and witty, and her suitors are significantly younger than she is (in contrast with Sense and Sensibility and Emma, which feature marriages of men who are sixteen years older than their wives). Although the ending includes a traditional reward for morality, Lady Susan herself is treated much more mildly than the adulteress in Mansfield Park, who is severely punished.
