Wub-e-ke-niew (1928–1997)

Hard read for the immigrants of North America to handle. By saying "immigrants", I mean all non-native, non-indigenous people. As it should be when confronting the uncomfortable truths of history and the legacy of the experiences meted out upon Native Nations.
It was one of the most outspoken and justice-driven perspectives I've ever read, and I could not put it down for long.
