Two Dark Reigns ( Three Dark Crowns 3 )

Katharine sits on the throne of Fennbirn. Dead bodies have washed up on the shore, but the real Mirabella and Arsinoe are in hiding. There are murmurs of dissent among the people of Fennbirn. The crown has been won, but unexpected renegade is about to wage a war of her own. The battle to be queen is far from done. -- adapted from jacket.
