The book I tell everyone to start with is 'Custer Died for Your Sins'. It’s not just foundational; it’s still the sharpest, funniest, and most direct introduction to Vine Deloria Jr.’s thinking. The chapter on anthropologists alone is worth the price of admission. Its influence is everywhere—you’ll see its arguments echoed in modern Indigenous scholarship and activism.
After that, 'God Is Red' is the logical next step. It completely re-frames Indigenous spiritual frameworks against Western religious traditions. The ideas are dense, but they’re world-building in a way that changed how I understood land, community, and time itself. Don’t rush it; let each chapter sit with you for a while.
