Whether viewed as an anthropological novel or novel anthropology, Mr. Storm's unusual book describing the collapse and destruction of the Plains Indian culture during the 1860's provides not only a stinging narrative of genocide but an introduction to Cheyenne mores and philosophy. The illustrations -- an outstanding feature -- include 25 line drawings, 150 half-tone photographs, and 13 color plates. Storm is an Indian and this is an affirmation of his heritage.
