Return to tumultuous Catalina, where peace is always tentative, and shadows always have teeth.

Eliza finds herself back in the dark clutches of Will Bronson, the King of Mineros. He parades her around the palace like a hard-earned trophy, and their impending wedding haunts her dreams. Even though her hope steadily dwindles, Nissa refuses to surrender. Finding herself out of options, Nissa strikes a dangerous deal with a mysterious entity, unlocking powers that could change everything–or destroy life as she knows it.

Meanwhile, Azure journeys to an enemy kingdom she believes to be crawling with others like herself: those with mutated abilities. While fighting mental and physical battles, she must discern who she can trust, and allies are not always what they seem.

In Aspia, Camille schemes to place one of the late King Louis' illegitimate heirs on the throne. If she's successful, it could tip the balance of power and secure their victory.

When faced with certain death, will they back down? Or will they fight tooth and nail to secure the peace they know Catalina is capable of?
