I wish I'd had Nabokov as a professor. I think he would have changed my life.
Instead, I will be content with his books. Unlike some other reviewers, I appreciate the scattered-ness of the book - it's sort of like a "who's who" of Native American tribes, and opens the door to some interesting discoveries and stories.
To say this book is well-researched does not do it credit - it is clear that Nabokov lives and breathes his work. This is no fluffy panoramic, but a guidebook to the peoples that we (us newcomers) have shunted aside, lied to, and visited with devastation. And that is the thread that gives an underlying message to this book, if nothing else does: that wherever we walk, beneath our feet are the sacred spaces of a people that we chose to push from their known worlds.
