The Kingdom of Gods
The Inheritance Trilogy - Book #3
by N.K. Jemisin
I'll be honest. The first two books in this series blew me away. This third one, not so much. It's told from the perspective of Sieh, the child god of the first two books. He's hit with an affliction that turns him into a mortal, but ages at a rapid pace.
Don't get me wrong, this is a good book, but it doesn't quite live up to the expectations I had after reading the first two.
Having said that, I'll definitely read anything Jemisin publishes.
