Query: An impressively engaging anthology of real-life stories

Keeping Heart On Pine Ridge is an impressively engaging anthology of real-life stories in which Vic Glover reveals the challenges, history, bonds, and rich traditions that infuse and reflect the stark realities of life on the Pine Ridge Indian Reservation. One of the very poorest Native American reservations in North America today, these are stories of the authors' family and friends, an enduring native American warrior culture, commodity foods, "rez dogs", harsh winters, and neighbors, as well as the social and political forces that shape the Pine Ridge native american community. Keeping Heart On Pine Ridge is especially recommended reading for students of 20th Century Native American Studies, as well as non-specialist general readers with an interest in contemporary indian life and culture on an American reservation.
