Polyamory Breakup Book

This book makes use of hierarchical primary/secondary terminology without ever challenging it and only mentioning alternative non-hierarchical ways of doing poly almost halfway through the book.
Even then, the author proves to be unable to move away from a hierarchical mindset as she calls egalitarian polyamory "multiple primary partners model" and solo polyamory "multiple non-primary partners model" which not only does not exactly roll off the tongue but frankly hilariously misses the point.

I'd been tolerating Labriola's framing of polyamory up until then, but what made me decide that this book isn't worth my time was THIS paragraph:

"However, some multiple primary partner relationships include one person who is considered the alpha, that is, they are considered "more primary" than any other partner".

If you're new to poly I highly encourage you to not tolerate this Animal Farm nonsense and being relegated into a 'secondary' role unless you know what that entails and being of secondary importance to a partner is exactly what you're looking for. Just know that this isn't normal and it's not the only way of being poly.
Polyamory isn't just about adding more partners to the mix but also, and perhaps most importantly, at dismantling our culturally ingrained assumptions and expectations around love.

Other that that - my biggest grievance with virtually all literature on polyamory is that it's actually literature on polyamory written by and for upper middle-class people. This book is no different.

It goes into poly breakups in a very superficial way, rattling off a series of potential situations without really going into anything very deeply, which honestly made it look like a book written for a monogamous audience that is interested in polyamory. I'm nowhere near a relationship expert and yet everything I've read here seemed incredibly trite.

Do yourself a favour and pick up Brigitte Vasallo instead.
