During her adventurous life, Norma Youngberg was a prolific writer and creative writing teacher. Her classic books such as Nyla and the White Crocodile, Singer on the Sand, Headhunter Hostage, and many others reveal the power of the gospel among primitive jungle peoples, and are favorites still today. Norma was born in Iowa and grew up in South Dakota. She came from a family of teachers, missionaries, and writers. Norma and husband Gustavus spent 20 years in the mission field, raised a family of six, and pioneered work among headhunters on the Tatau River of Sarawak.
