My only complaint is that I wish it was longer. I wanted more of our protagonists as I felt that we had only scratched the surface of who they were. It was easy to form relational connections as Kim made them easily accessible in how they and their motives were written. As for the antagonist, I also wanted more of their backstory and the secrets that they are using to maintain control and power. 

The pacing moves in this story, you will want to slow down as the author is not wasting time in getting to their end game. I highly recommend this read.
