Quo Vadis? is a sweeping historical novel set in Nero's Rome, where a Roman nobleman falls in love with a Christian woman and is drawn into the early church's struggle for survival. Against a backdrop of imperial decadence, persecution, and the Great Fire of Rome, the story contrasts cruelty and spectacle with faith, sacrifice, and spiritual transformation. Sienkiewicz combines romance, political intrigue, and religious drama into a vivid portrait of a civilization at a turning point.
