I'm looking for some book recs. Specifically, I'm looking for (fiction) books that deal with poly-amorous relationships. Not like, a couple inviting another person into their bed every once in a while but an actual relationship between multiple people. Sex is encouraged but not necessary. I mostly want a book about three or more people working their way through life together or something.
I just bought a Kindle so ebooks are encouraged but again, not necessary.
So, yeah. Does a book like this exist?
