N. K. Jemisin  - only author to have won the hugo for best novel three years in a row, only author to have won it for every book in a series and, to top that, the only author who has ever set out to write a trilogy and instead managed to wrap it up as a duology instead.
Truly, there is nothing she cannot do.

This book was a delight. It was aware that it was incredibly weird and eldritch and does so many fun things all at once while knowing, in its heart, in the best traditions of Terry Pratchett, that squamous tentacles and beings from the horrific depths of reality are only as good as the characters fighting them. And it delivered.
