Often we are limited by our own imagination. This book provides counter-narratives to our current societal expectations to help the reader imagine better ways to structure society. 

The first part of this book tries to show that many of the undercurrents in our society (marriage, patriliniality, private property, etc.) arise from a particular historical setting and that alternative worldviews are possible.

The book then describes how people have organized in communal situations, what has worked, and what hasn't. It covers a wide range of topics from the philosophical underpinnings of the founders to American tax law.

Chapters are organized by issue, which allows for one to understand how society can be restructured, but it prevents diving deep into a particular communal situation. Overall, I think the book's structure helps provide for a good overview. 

Most of the examples in the book center around Europe and North America. I would love to have seen more examples from throughout the world. 

While the author did her research and is clearly knowledgeable about the field, she is unapologetically in support of creating an alternative society, even if she recognizes that other structures aren't perfect either.
