The Hunchback of Notre-Dame by Victor Hugo

Hugo's grand medieval melodrama tells the story of the beautiful Esmeralda, a gypsy girl loved by three men: Archdeacon Frollo, his adoptive son Quasimodo, bell-ringer of Notre-Dame cathedral, and Captain Phoebus. Falsely accused of trying to murder Phoebus, who attempts to rape her, Esmeralda is sentenced to death and rescued from the gallows by Quasimodo who defends her to the last.
The subject of many adaptations for stage and screen, this remains perhaps one of the most romantic yet gripping stories ever told.
