N. K. Jemisin.
Incredibly powerful writing and writes science fiction and fantasy that I actually enjoy reading after getting disillusioned with the Tolkein lineage for its deep racism & colonialism. Her Stone Sky series is wildly creative in terms of world building, had an excellent epic plot to rival any of the other greats you could name, has complex and compelling characters, and a satisfying conclusion. She's won the right awards, and I hope that that translates into a lineage of people building in her ideas as rich as Tolkien's.
