I read the Broken Earth books and thoroughly enjoyed them (especially the first). I found Jemisin's worldbuilding and protagonists writing to be very compelling.
I strongly recommend to read at least the Fifth Season to see if her writings are to your taste.
The fact that some would object that she is a Sci-fi writer seems... rather reductive to me at the least. Sure Jemisin does not write "hard" SF, and the Broken Earth has some strong fantasy tropes. But so did Frank Herbert and Ursula Le Guin, two among the most revered writers of the genre.
[EDIT] I should not even say that she does not write hard SF, since I did not read her other books (yet). I should have kept it at "The Broken Earth trilogy is not hard SF"
