I remember reading this years ago, and I was reminded of it again after reading Fordlandia, which I reviewed here as well. This book does two things. It gives you a biography of Elisabeth Nietzsche, sister of the philosopher. Two, it gives you the story of the Aryan community her husband and her established in the middle of the Paraguayan jungle. The author went there to find the few remaining descendants of that community. I remember liking the book, and this was probably one of my first reading forays into that subgenre of books some people call micro-histories. This is one book I would recommend if you like the lesser known parts of history.
