Books
There are actually plenty of books out there on polyamory but also some good books on relationships generally. These are my recommendations. They are also prompts for reviews at some point.
A World Beyond Monogamy
My new favourite book on non-monogamy. Almost a textbook feel yet highly readable. A really nice blend of journalistic structure with quirky British humour by Jonathan Kent.
Marriage, a History
You don't know marriage until you have read this book. Stephanie Coontz casts a historian’s eye over the institution. It turns out to have changed rather a lot over time and is only accelerating.
Sex at Dawn
This book seems to have been a gateway for many people. It takes an anthropological look at human relationships with a fiercely critical view of monogamy.
Why We Love
Anna Machin goes right down to the nuts and bolts of Love, the hormones and neural circuits before building up to the psychological and social structures.
The State of Affairs
I came at this book by Esther Perel with a deeply-rooted suspicion of anything that might be validating cheating behaviour. However, the beautifully written book actually takes a deep and nuanced look at the institution of marriage and why monogamy doesn’t work for many people.
