I re-read it with my kids, and yes, he was "part" Native, like his "ex," the amazing Louise Erdrich, who was, inspite of everything, his "soul mate." They wrote that book, and all of their books, sitting together, each one reading sections of their work together, commenting, crafting, sculpting... I used to want a relationship just like theirs...and then, the reality came to light...sigh...I don't know if Louise will EVER recover, but...their books, no matter what, will always be classics. There's a lot of controversy, and some Native scholars, as usual, don't think they deserve to be called "Native" authors. But those are the ones Sherman got after, when he asked them about their blonde, blue-eyed wives. I will never forget that master stroke--all those academics pontificating, and then Sherman came in and said, "Who are YOU all to talk?" It was great theater, and he made an excellent point!
