Echo Desjardins, a thirteen-year-old Metis girl, is struggling with feelings of loneliness while attending a new school and living with a new foster family. Then an ordinary day in Mr. Bee's history class turns extraordinary, and Echo's life will never be the same. During Mr. Bee's lecture, Echo finds herself transported to another time and place--a bison hunt on the Saskatchewan prairie--and back again. In the following weeks, Echo slips back and forth in time. She visits a Metis camp, travels the old fur-trade routes and experiences the perilous era of the pemmican wars.
