Impostors — David Drake (1)

Ages 10 to 14: Twelve year old twin boys were separated at birth. One was raised as a Cherokee and the other a white boy. In 1870, Kansas, they discover each other while on separate journeys to Red Bend hoping to discover who they were. They soon accept that they are twin brothers, begin having dangerous and exciting adventures together, and find the blending of their backgrounds makes for a remarkable life together. (This story uses the same setting, ten years earlier, than the six book series, The Doc and Johnny Old West Mysteries.)
In Book Two, Impostors, the boys find themselves up against a gang of men who are trying to stir up trouble between the residents of Kansas and the peaceful Indians who live there. They get caught in a waterfall, captured by the head bad guy, almost lose a good friend to a snake bite, and meet a new friend there age from the Arapaho Tribe who is trying to get medical help for his grandmother. Lots of conversations about prejudice and mixed race children. If they are lucky, they just may survive to star in book three of the series (smile!).
