How to Swallow the Moon, by Isabelle Yap

How to Swallow the Moon is a Locus Award 2019 finalist. And an OK choice I guess, though it's a really old story that gets retold a lot.  The only twist, and anymore it's a pretty mild one, is that the lovers from extremely different social castes, where the lower caste one is the tutor to the higher one, is that they are both women.  Now, the ending does in fact have a twist worth the read, and that makes it worthy of consideration.  So I got a surprise out of that.  It's a good story, I can recommend it.
