The Sister by Sung-Yoon Lee
7 out of 10

The Mount Paektu bloodline [a.k.a the Kim family dynasty] represents the most totalitarian regime in the world.  Three generations after its founding, Kim Jung Un became the Supreme Leader upon his father's death in 2011.  The family is very secretive.  All three of the Supreme Leaders have had multiple wives, mistresses, and consorts.  Not all children are known to the press or the outside world.  Some children attend school in other countries under fake names.  On occasion, adult family members are exiled or killed to further concentrate power.  Kim Yo Jong is the younger sister of KJU.  Groomed for leadership, she currently serves as a diplomat and public affairs minister.  Her talent is noticeable and she appears to be a strong asset to her deified brother.  Speculators speculate that this 36-year-old princess has a chance at being the next Supreme Leader.
