Glitter: It's a book about how early man (pre-agricultural man) was naturally polyamorous. It kind of disproves the standard narrative that says that monogamous pair bonding is "natural" to our species. Full of awesome information, anthropological, archeological, sociological info that proves that we were never naturally meant to be monogamous and that monogamy arose out of a need to pass down land and ownership of property in our post agricultural societies. Really cool stuff whether you agree with it or not. I'd highly recommend it.
Magdalena: Yes! I found the book to be incredibly validating. I knew polyamory was always the right choice for me whether It was prehistorically preordained or not, but the book painted such a beautiful picture as human kind being predisposed to positivity and sexual freedom. Also, the feminist aspects were wonderful. Yes, it's OK that I'm always horny :P
