The Killing Moon

The Killing Moon - N.K. Jemisin

I love N.K. Jemisin's world building even though I had a hard time keeping the various castes straight an following the first 3rd of the story. But once the two strands of the story met and intertwines, I was just swept along.  

 

As a side-note, I was surprise to find more than a dozen books published in the last 10 years titled The Killing Moon, A Killing Moon or just Killing Moon.
