Now in paperback, here is the inspiring story of Sacagawea, the only Native American included in Lewis and Clark's historic expedition, part of the New York Times-bestselling biography series about heroes for ages 5 to 9. This book spotlights Sacagawea, the only girl, and the only Native American, to join Lewis and Clark's Corps of Discovery, which explored the U.S. in the early 1800s. As a translator, she helped the team communicate with members of the Shoshone tribe across the continent, carrying her child on her back the whole way.
