People familiar with studies of the Plains Indians and their culture already know that this is the defininitive book on the Cheyennes. The details of their history, culture, and religion are fascinating. However, those just beginning to dabble in this area of study should be warned, it may be more than they are looking for right now. For example, the alliances and warfare between the Cheyenne and other tribes would be very difficult to follow if you didn't already know a little bit about who they were and how their migratory paths crossed,etc. Once you've done a fair amount of study on the subject, however, your library will not be complete without it.
