On an island in Eastern Indonesia, lived a semi-nomadic group of hunters and gatherers with a fearsome reputation that made many unwilling to even step foot into their territory. In 1982, a small group of outsiders took that very step. In this gripping and honest account, John and Betty describe their experience as they along with their co-workers, moved into the jungles of Indonesia to live among the Tugutil people. Working tirelessly, amidst many challenges and impossible circumstances, John and Betty strived to learn the people's language and culture, and understand their way of life, all for the sake of being able to communicate clearly the lifesaving message they had come to bring. The Tugutil provides a firsthand account of how God worked in the hearts of an entire people group, totally transforming them from the inside out.
