Philip J. Deloria

Deloria's second book, Indians in Unexpected Places (2004), explores stereotypes of Native American people which confine them to the past and analyzes the seeming disunity between Indian people and modernity. Indians in Unexpected Places received the John C. Ewers Prize for Ethnohistorical Writing in 2006 from the Western History Association.
