Elizabeth McNeill is the pseudonym of an American author who published the semi-autobiographical erotic memoir *Nine and a Half Weeks* in 1978. The novel, which depicts an intense and psychologically complex BDSM relationship in 1970s New York City, became an international bestseller and was adapted into the 1986 film starring Kim Basinger and Mickey Rourke. Writing in the literary erotica genre, McNeill is known for her frank, introspective exploration of female desire, power dynamics, and emotional vulnerability within sexual relationships. She maintained her anonymity throughout her career, adding mystique to her work. The book's raw honesty and psychological depth distinguished it from conventional erotic fiction of its era.
