•Why it earns a slot
Hugo's novel single-handedly revived public interest in Gothic medieval architecture, directly influencing the restoration of Notre-Dame de Paris, while establishing the archetype of the outcast hero whose inner nobility is invisible to a society that judges only by appearance.
Set in 15th-century Paris, the novel follows Quasimodo, the deaf and deformed bell-ringer of Notre-Dame Cathedral, who falls in deeply devoted love with the Romani dancer Esmeralda. The archdeacon Claude Frollo, consumed by a destructive obsession with Esmeralda, engineers her condemnation and execution, while Quasimodo, unable to save her, kills Frollo and then dies beside Esmeralda's body in the charnel house where he has retreated to mourn her.
