Originally published under the pseudonym "Victoria Lucas" in 1963, the novel is semi-autobiographical, with the names of places and people changed.

Plath died by suicide a month after its first UK publication.  The novel was published under Plath's name for the first time in 1967 and was not published in the United States until 1971, in accordance with the wishes of both Plath's husband, Ted Hughes, and her mother.
