This book tells the story of Robert, a young man of white American and Sioux parents, who is coming of age and maturing in faith as the brutal Sioux Rebellion of 1862 unfolds. He meets and falls in love with an Ojibwa girl and must rescue her on two occasions, first from the Pawnee Skidi tribe who want to use her as a living sacrifice, and second from the son of the chief of the rebelling tribe. The story shows how Robert and his family rely on their Christian faith through their troubles and are delivered in the end.
