In 1934, Launi Fairfield goes to the jungles of Peru to translate the Bible into an Indian dialect. She thought missionary work would be exciting, but her days are taken up with the tedious translation project.
Miles Stone has been a missionary doctor for ten years. He's a confirmed bachelor, not wanting to be saddled with a wife and children as he moves around to the different Peruvian tribes. He's content with his life, until he meets Launi.
Together, they end up having more adventure than Launi ever bargained for. They battle snakes, jaguars, sickness, earthquakes, and an Indian chief who wants to add Launi to his harem. Will they trust God for all their tomorrows?
