Historian, John W. W. Mann offers an absorbing and richly detailed look at the life of Sacajawea's people before their first contact with non-Natives, their encounter with the Lewis and Clark Expedition in the early nineteenth century, and their subsequent confinement to a reservation. He follows the liquidation of the Lemhis’ reservation in 1907 to their forced union with the Shoshone-Bannock tribes of the Fort Hall Reservation and recounts their continuing struggle to maintain their political, economic, and cultural integrity.
