This epic tale follows Ishmael's narrative of the obsessive quest of Ahab, captain of the whaling ship Pequod, for revenge against Moby Dick, the giant white sperm whale that bit off his leg. As the crew pursues the whale across the seas, the novel explores themes of obsession, faith, the conflict between good and evil, and humanity's relationship with nature, all while providing detailed insights into the 19th-century whaling industry.
