Reading about Native Americans

Anything Native American is right up my alley. I love the culture and how pure these peoples were before the old world met the new. I'm reading a book called Hidden Roots and it a captivating tale of a young boy who is discovering his ancestry. it really hits on the plights of modern Native Americans many of whom (about 80%) live below the poverty rate, alcoholism is rampant, and domestic violence is the norm. This story is set not many years ago, around 30, and it hits on a lot of the racism toward Native Americans. I'm not finished so I'm just guessing right now how it will end.
