Lolita by Vladimir Nabokov

Lolita is a novel written in English and published in 1955 in Paris and 1958 in New York by Vladimir Nabokov. It was later translated by its Russian-native author into Russian. The novel is notable for its controversial subject: the protagonist and unreliable narrator, middle-aged literature professor Humbert Humbert, is obsessed with the 12-year-old Dolores Haze, with whom he becomes sexually involved after he becomes her stepfather. His private nickname for Dolores is Lolita.

Plot summary
Humbert Humbert, a literary scholar, has harbored a long-time obsession with young girls, or "nymphets". He suggests that this was caused by the premature death of a childhood sweetheart, Annabel Leigh. After an unsuccessful marriage, Humbert moves to the small New England town of Ramsdale to write. He rents a room in the house of Charlotte Haze, a widow. While Charlotte shows him around the house, Humbert meets her 11-year-old daughter, Dolores—or Lolita—with whom he immediately becomes infatuated, partly due to her uncanny resemblance to Annabel. Humbert stays at the house only to remain near her. While he is obsessed with Lolita, he disdains her crassness and preoccupation with contemporary American popular culture, such as teen movies and comic books.
While Lolita is away at summer camp, Charlotte, who has fallen in love with Humbert, tells him that he must either marry her or move out. Humbert agrees to marry Charlotte in order to continue living near Lolita. Charlotte is oblivious to Humbert's distaste for her, as well as his lust for Lolita, until she reads his diary. Learning of Humbert's true feelings and intentions, Charlotte plans to flee with Lolita and threatens to expose Humbert as a "detestable, abominable, criminal fraud." Fate intervenes on Humbert's behalf, however; as she runs across the street in a state of shock, Charlotte is struck and killed by a passing car.
Humbert picks Lolita up from camp, pretending that Charlotte has been hospitalized. Rather than return to Charlotte's home, Humbert takes Lolita to a hotel, where he gives her sleeping pills. As he waits for the pills to take effect, he wanders through the hotel and meets a man who seems to know who he is. Humbert excuses himself from the strange conversation and returns to the room. There, he attempts to molest Lolita but finds that the sedative is too mild. Instead, she initiates sex the next morning, having slept with a boy at camp. Later, Humbert reveals to Lolita that Charlotte is dead, giving her no choice but to accept her stepfather into her life on his terms or face foster care.
Lolita and Humbert drive around the country, moving from state to state and motel to motel. Humbert sees the necessity of maintaining a common base of guilt to keep their relations secret, and wants denial to become second nature for Lolita; he tells her if he is arrested, she will become a ward of the state and lose all her clothes and belongings. He also bribes her for sexual favors, though he knows that she does not reciprocate his love and shares none of his interests. After a year touring North America, the two settle down in another New England town, where Lolita is enrolled in a girls school. Humbert becomes very possessive and strict, forbidding Lolita to take part in after-school activities or to associate with boys; most of the townspeople, however, see this as the action of a loving and concerned, while old-fashioned, parent.
Lolita begs to be allowed to take part in the school play; Humbert reluctantly grants his permission in exchange for more sexual favors. The play is written by Clare Quilty. He is said to have attended a rehearsal and been impressed by Lolita's acting. Just before opening night, Lolita and Humbert have a ferocious argument; Lolita runs away while Humbert assures the neighbors everything is fine. He searches frantically until he finds her exiting a phone booth. She is in a bright, pleasant mood, saying she tried to reach him at home and that a "great decision has been made." They go to buy drinks and Lolita tells Humbert she doesn't care about the play, rather, wants to leave town and resume their travels.
As Lolita and Humbert drive westward again, Humbert gets the feeling that their car is being tailed and he becomes increasingly paranoid, suspecting that Lolita is conspiring with others in order to escape. She falls ill and must convalesce in a hospital; Humbert stays in a nearby motel, without Lolita for the first time in years. One night, Lolita disappears from the hospital; the staff tell Humbert that Lolita's "uncle" checked her out. Humbert embarks upon a frantic search to find Lolita and her abductor, but eventually he gives up. During this time, Humbert has a two year relationship (ending in 1952) with an adult named Rita, who he describes as a "kind, good sport." She "solemnly approve[s]" of his search for Lolita. Rita figuratively dies when Humbert receives a letter from Lolita, now 17, who tells him that she is married, pregnant and in desperate need of money. Humbert goes to see Lolita, giving her money in exchange for the name of the man who abducted her. She reveals the truth: Clare Quilty, an acquaintance of Charlotte's, the writer of the school play, and the man Lolita claims to have loved, checked her out of the hospital after following them throughout their travels and attempted to make her star in one of his pornographic films; when she refused, he threw her out. She worked odd jobs before meeting and marrying her husband, who knows nothing about her past. Humbert asks Lolita to leave her husband, Dick, and live with him, to which she refuses. He gives her a large sum of money anyway, which secures her future. As he leaves she smiles and shouts goodbye in a "sweet, American" way.
Humbert finds Quilty at his mansion; he intends to kill him, but first wants him to understand why he must die; he took advantage of a sinner (Humbert), he took advantage of a disadvantage. Eventually, Humbert shoots him several times (throughout which Quilty is bargaining for his life in a witty, though bizarre, manner). Once Quilty has died, Humbert exits the house. Shortly after, he is arrested for driving on the wrong side of the road and swerving. The narrative closes with Humbert's final words to Lolita in which he wishes her well, and reveals the novel in its metafiction to be the memoirs of his life, only to be published after he and Lolita have both died.
According to the novel's fictional "Foreword", Humbert dies of coronary thrombosis upon finishing his manuscript. Lolita dies giving birth to a stillborn girl on Christmas Day, 1952.
