The Crossing — Donna Jo Napoli

This young, lyrical picture book reveals the adventure and natural wonders that Lewis & Clark encountered on their Western expedition in the early 1800s. Told from the point of view of Jean Baptiste Charbonneau, the baby on Sacagawea's back, this story offers a fresh perspective of a young country and gives voice to a character readers will already be familiar with--at least visually (the baby is shown on the golden Sacagawea dollar).
