Lewis and Clark's Journey of Discovery put their names in the history books, but alongside them is found the name of Sacagawea, the young Shoshone woman who acted as guide and interpreter on their expedition from St. Louis to the Pacific. With her husband and infant son, Sacagawea accompanied the Corps of Discovery through danger, illness and extremes of weather, sharing both their despair and their triumph.Basing her book on the journals of Lewis, Clark and other members of the expedition, award-winning author Judith St. George shows how this remarkable woman earned her place in history.
