Twilight Sleep is a novel by American author Edith Wharton and was first published in 1927 as a serial in the Pictorial Review before being published as a novel in the same year. The story, filled with irony, is centered around a socialite family navigating the New York of the Jazz Age and their relationships. This novel landed at number one on the best-selling list just two months after its publication and finished the year at number seven. Even as a best selling novel Twilight Sleep was not well received by critics at the time, who, while appreciating Wharton as a writer, struggled with the scenarios and characters she had created in the novel. While it was not considered as such in its own time period, today Twilight Sleep is widely considered to be a modernist novel as it employs modernist literary devices, such as an ever changing narration among the novel's characters and a close examination of the characters' self-identities and relationships with one another.
