Three Partitions
by Bogi Takács
Warning: some body horror. It didn't affect my enjoyment, though.
The flashbacks and multiplicity of perspectives were confusing, the first time around---I had to read it twice in a row. On the second read I got it and quite liked it, though I would agree with other reviewers that the world-building is stronger than the plot.
This is surprisingly not-queer for a story about a person who's considered non-binary by her community, but it made sense in the context.
