Lolita is a 1955 novel written by Russian-American novelist Vladimir Nabokov. The novel is notable for its controversial subject: the protagonist and unreliable narrator, a middle-aged literature professor under the pseudonym Humbert Humbert, is obsessed with a 12-year-old girl, Dolores Haze, whom he kidnaps and sexually abuses after becoming her stepfather. "Lolita", the Spanish nickname for Dolores, is what he calls her privately. The novel was originally written in English and first published in Paris in 1955 by Olympia Press.
