One of the first known novels by a Native American woman,Cogewea(1927) is the story of a half-blood girl caught between the worlds of Anglo ranchers and full-blood reservation Indians; between the craven and false-hearted easterner Alfred Densmore and James LaGrinder, a half-blood cowboy and the best rider on the Flathead; between book learning and the folk wisdom of her full-blood grandmother. The book combines authentic Indian lore with the circumstance and dialogue of a popular romance; in its language, it shows a self-taught writer attempting to come to terms with the rift between formal written style and the comfort-able rhythms and slang of familiar speech.
