Sacagawea, a young Native American woman, accompanied by her infant and her cruel husband, experiences joy and heartbreak when she joins the Lewis and Clark expedition seeking a way to the Pacific.

When young Sacagawea first lays eyes on the white men coming up the river, she cannot imagine the impact they will have on her life-and she on theirs. For the men coming up the river are about to make history, and she is going to help them.

Sacagawea joined the Lewis and Clark team as an interpreter and guide. Her knowledge of the language, land, and people of the unchartered West made her an integral part of their success.

Like the author's Newbery Medal-winning classic Island of the Blue Dolphins, Scott O'Dell's Streams to the River, River to the Sea is a gripping tale of survival, strength, and courage.
