The primary purpose of this study is to demonstrate that the most consistent themes in the selected novels are love and happiness. The novels are: Bonjour tristesse, 1954; Un certain sourire, 1956; La chamade, 1965; Les merveilleux nuages, 1961; Un profil perdu, 1974; Aimez-vous Brahms, 1959; Le garde du coeur, 1968; and De guerre lasse, 1985. Sagan challanges her heroines, and her readers, to find happiness. Each of the heroines handles the individual search for love and happiness in her own specific way. Throughout the novels, love represents pain and suffering as Sagan describes the emptiness of life in modern society. Her works show the futility of love in a world preoccupied by superficial things.
