Quite a full re-creation of both place and character figure in this biography of Sacajawea. Starting with her girlhood and the varied life she led, shunted as a captive from tribe to tribe, the reasons for her knowledge of the land and her wide curiosity about people and nature become inherent parts of the story. It is good reading too, as it moves quickly into her marriage to Toussaint Charbonneau, the headstrong trapper who was a far less successful guide in the Lewis and Clark expedition than his wife. No bones are made about the various controversies between them and though there is not a full picture of the journey- its elements have long been open to historical speculation. Sacajawea is taken on into old age too, with her activities as ambassador and their resulting effects in better understanding.
