Barbara M. Cooper looks closely at the Sudan Interior Mission, an evangelical Christian mission that has taken a tenuous hold in a predominantly Hausa Muslim area on the southern fringe of Niger. Based on sustained fieldwork, personal interviews, and archival research, this vibrant, sensitive, compelling, and candid book gives a unique glimpse into an important dimension of religious life in Africa. Cooper's involvement in a violent religious riot provides a useful backdrop for introducing other themes and concerns such as Bible translation, medical outreach, public preaching, tensions between English—speaking and French—speaking missionaries, and the Christian mission's changing views of Islam.
