Buffy Sainte-Marie, native Canadian singer-songwriter, social activist and member of the Cree First Nation, is now in her 70s and has co-authored the first and only authorized biography that tells her story — a story of a woman whose career has stretched from the coffeehouses of Toronto and Greenwich Village in the early 1960s to concert halls around the world. Buffy Sainte-Marie: The Authorized Biography is co-authored with Andrea Warner.
