Told from the point of view of Jean Baptiste Charbonneau, the baby on Sacagawea’s back, this breathtaking picture book reveals the adventure and natural wonders that Lewis and Clark encountered on their Western expedition in the early 1800s. Donna Jo Napoli’s lyrical text and Jim Madsen’s majestic artwork offer a fresh perspective on the remarkable sights and sounds of a young country, and give voice to a character readers are already familiar with: baby Charbonneau is shown on the golden Sacagawea dollar.
