Erdrich puts Sacagawea’s story into perspective, clearly representing her importance to the success of the Lewis and Clark Exploration of Discovery. The lusciously colored oil paintings complement the tale, making it all the more creditable in their historic accuracy. Erdrich’s narrative is both straightforward and lyrical—and always interesting. Both the foreword, discussing the oft-maligned spelling of Sacagawea, and the end note and timeline dealing with Sacagawea’s life after the completion of her part in the voyage, help readers pull all of the other information about this brave and intelligent explorer into a cohesive whole with the events of the time. Absorbing, interesting, beautiful—with all the makings of a classic. (Picture book/biography. 6-12)
