So, I am not sure if this is meant to be a morman family or just a random group of polygamist. But it looks interesting. I understand polyamory while remaining single. After marriage I think it would get trickier. You through kids into the mix......and I am really confused! Maybe it is just the whole mess I see in my family of divorce, half siblings, step parents etc.
Anyway......this series looks intereting:
