Runs With Courage by Joan M. Wolf
Four Winds is a Lakota girl who lives on a reservation in the 1870's. It has been decided by the tribe elders to send her away with white people to a school that educates Lakota girls. What she doesn't know is that her tribe made a deal with the whites to receive food in exchange for letting them take Four Winds to their school. She later learns about this and decides to make great sacrifices to endure the hardships of the school to make sure her people survive.
This story focuses on maintaining your culture even while being forced to accept a new one. During the 1870s, the government was at war with indigenous people and ended up nearly wiping out entire Native American cultures. This story is definitely one that shows the darker side of American history from a perspective of a young girl that could have lived through it. It is a must read for anyone learning about the history of the United States and the Native Americans.
