The Whale Tooth by Jack London

A missionary named John Starhurst arrives on a Pacific island determined to convert its people, but he underestimates the power of their ancient customs. He confronts a warrior chief and the sacred symbol of the whale tooth, which carries deadly consequences. As cultures clash, the missionary’s idealism meets the harsh reality of tribal justice. The plot builds to a dramatic and violent climax. It’s a powerful tale of cultural misunderstanding and the limits of belief.
