The Bell Jar by Sylvia Plath
The Bell Jar is American writer and poet Sylvia Plath's only novel, which was originally published under the pseudonym "Victoria Lucas" in 1963. The novel is semi-autobiographical with the names of places and people changed. The book is often regarded as a roman à clef, with the protagonist's descent into mental illness paralleling Plath's own experiences with what may have been either bipolar disorder or clinical depression. Plath committed suicide a month after its first publication.
