The King's 100

Sixteen-year-old Piper Parish, princess of the loveless, STEM-only kingdom of Capalon, is a disappointment to her citizens and to her older sister, the queen. When Piper receives an anonymous note stating her mother is still alive and living in the enemy kingdom of Mondaria, Piper chooses to risk death in effort to prove once and for all that she's not just the queen's defective little sister. With the companionship of Chip, a piece of tech embedded in her wrist, Piper flees Capalon and enters a world where love and emotional expression are unrestricted.

Posing as a singer for the enemy king’s court of performers, the King’s 100, Piper risks death if she is revealed to be the Capalon princess but discovers that living a life without the freedom to love might actually be the most dangerous risk of all.
