I don't recall how I discovered Octavia E. Butler twenty years ago but I'm pretty sure I noticed N.K. Jemisin thanks to a review in the Washington Post that compared her work to Butler's Parables books.
The Fifth Season is the beginning of an epic, laying the foundation of a world with a magic system and a hierarchical guild that employs it. A world, like ours, that is changing, changing in ways the humans within it do not expect and may not survive. If you're watching fantasy series via streaming ... the world of The Wheel of Time is probably the best match in terms of feel and scope.
