Roman highlighting the lifestyle and traditions of the Lakota (Sioux one of the 7 tribes). The plot is simple and allows you to experience the harmony between men and nature. (Environmentally) The Lakota were described as deeply human. Warriors to protect the tribe and hunters to ensure their subsistence (not kill beyond the needs). The "sacred Fer" (gun) appears throughout the narrative as the inexorable change to come in the life and habits of these tribes. To refuse would mean an inevitable weakening. Accepting it would disrupt the philosophy of the Lakota warrior.
This novel is beautifully written, simple and powerful at once. The messages conveyed are tragically modern (the return to nature, the damage caused by the "progress" technique, ...) I relived some of the westerns of my childhood while avoiding the clichés about "the Indian." The history of this people is sadly similar to that of Australian aborigines; the gradual extinction of a civilization and knowledge.
