Which American author wrote "The Bell Jar"?

Sylvia Plath is the author of "The Bell Jar," which was published in 1963 under the pseudonym Victoria Lucas. This semi-autobiographical novel explores themes of identity, mental illness, and the struggles of young women in a society that often feels oppressive. Plath’s own experiences with depression and her upbringing heavily influenced the narrative and character development within the novel, making it both a deeply personal work and a critical commentary on societal expectations.

The other authors listed, while significant figures in American literature, wrote different works that explore varying themes and styles. Virginia Woolf is known for her modernist narratives and stream-of-consciousness writing, Toni Morrison focuses on African American experiences and culture, and Flannery O'Connor is recognized for her Southern Gothic style. Each of these authors has made substantial contributions to American literature, but they are not connected to "The Bell Jar" in the same way that Plath is.
