Useful girl

A novel combining the stories of a contemporary Montana teen and an 1870s Cheyenne girl tells of Erin, a 17-year-old still raw from her mother's death and her father's distance, who doesn't know what to feel when her father's construction company unearths the bones of a Cheyenne girl. Erin's romance with a young Indian man, Charlie White Bird, dovetails with her imagined story of the girl, whom she calls Mo'é'ha'e. As Erin struggles to deal with being a white girl in love with a Native American, Mo'é'ha'e gradually overcomes her hatred for a captured white boy.
