He studies the effects of shifting governmental attitudes and policies on the Florida Native Americans during the past quarter-century. He also charts the social, economic, and political experiences of the tribe during these volatile decades. By the end of the account, readers understand that the Seminole tribe has become organized, functioning, and sovereign, with a stable economic base. The author has made extensive use of oral history from tribal elders as well as the memoirs and records of Florida congressional leaders
