Can the whole tribe depend on her?

Being the oldest unmarried girl in her Blackfoot tribe is misery for fifteen-year-old Sweetgrass, but her father feels she's not ready for the hard work and responsibility that come with being an Indian wife. Then, during the cold prairie winter, a smallpox epidemic breaks out. With the men away at war, Sweetgrass is one of the few women left to fight for the survival of her tribe. This is her chance to prove her maturity, but is she strong enough to fight the cold, hunger, and disease?
