This is the story of two very different women traveling in the American West in 1847. Emily Lamb is an idealistic young woman who is driven from her home by a mob, and becomes the sole survivor of her family. Sariah Porter grew up on the frontier, and is the granddaughter of an Indian Medicine man. As they travel along the Mormon Trail, they grow in friendship--innocent of the terrible danger shadowing them. They travel through Indian Country, across the plains, and over the Rocky Mountains. Along the way, they meet a variety of characters, some good, some less than honest, and all very human. When they near the end of the trail, Emily must choose between becomming the second wife in a polygamous marriage, or a spinster on the trail with Sariah.
