Mosi is a 10-year-old native American girl living with her family on a sheep ranch just outside of Santa Fe, New Mexico. Her mother is a potter who wants to keep alive the art of their culture. Her father runs the ranch, taking care of their sheep and llamas.

In the summer, Mosi visits her grandmother, who lives on the reservation. She listens as her grandmother tells old stories about their people, and learns how to spin yarn from sheep's wool. Sometimes they go to a pow-wow and watch the dancers in their beautiful costumes. When asked why she doesn't leave the reservation for Santa Fe, Grandmother says, "My heart cannot walk two paths." Mosi wonders if she can be a girl that does.
