Kon-Tiki by Thor Heyerdahl is a non-fiction book recounting Heyerdahl's daring 1947 expedition across the Pacific Ocean on a balsawood raft. Heyerdahl and his crew set out to prove that pre-Columbian South Americans could have settled Polynesia. The book details their voyage from Peru to Polynesia, encountering various challenges including storms, sharks, and navigational difficulties. Ultimately, their successful journey supported Heyerdahl's theory and captured the world's imagination, challenging conventional wisdom about early human migration.
