Grace and Fury by Tracy Banghart

In a world where women have no rights, sisters Serina and Nomi face two very different fates: one in the palace, the other on an island prison where women must fight to survive.

Serina has spent her whole life preparing to become a Grace – selected to stand by the heir to the throne as a shining example of the perfect woman.

But her headstrong and rebellious younger sister has a dangerous secret, and one wrong move could cost both sisters everything. Can Serina fight? And will Nomi win?
