I really enjoyed this book. It's fascinating from both a narrative stand point and a history standpoint. Seeing how lesbian it actually is (especially for being published in 1980) is amazing. I won't go into the history of queer publishing, but to have a novel like this be as explicit as it is (not spicy explicit, but there is lesbian sex and showing of relationships) is a wonder (even though knowing the 80's were better for publishing a novel like this than past decades). 
It's also interesting reading this 45 years after it was published and being able to relate to the apocalypse thinking and how the new world functions. Seeing how we're shifting back to traditional gender roles and religion here in the west, the set up of the world outside Demeter isn't shocking. It's shocking how much things haven't changed since this was published. 
A very cool piece of queer literature that I would've never known about if not for picking it up at a used bookstore.
