I had a similar experience -- I did enjoy it, and some parts genuinely moved me, but the last quarter or so was a bit of a slog.

I will say that I enjoyed her short stories a lot more! They are fairly deep but entertaining, with great twists and surprises

The Wind's Twelve Quarters is a good anthology -- in that one, I liked The Rule of Names, Semley's Necklace and The Word of Unbinding. In another anthology (I think), Direction of the Road -- phenomenal. Most of these can be found standalone online

The Ones Who Walk Away from Omelas I enjoyed less, but it's a short read and fairly important culturally. NK Jemisin, who wrote the Broken Earth trilogy (highly recommend it), wrote a sort of tongue-in-cheek short-story in response to it called The Ones Who Stay and Fight -- also worth reading.
