Daughter and heir to the throne, Mancella Cliff yearns for a life without bloodshed. But as a child, she emerged from the Broken Citadel with the power to summon animals - only after killing them first. Her magic is a constant reminder of the horrors her father, the ruler of the realm, has forced upon her to strengthen their power. Silver is a charming thief struggling to survive in a world torn apart by Mancella’s father’s reign. When a mysterious benefactor recruits him for the heist of a lifetime, a chance to rob the castle, Silver relishes the opportunity for a real future - and revenge. But he'll have to manipulate Mance and earn her trust to pull it off. As the deception and carnage mount, Mance must find a way to save her realm without becoming the ruthless monster she's been bred to be. And when Silver discovers that his actions are fueling the violence that Mance wants to prevent, he'll have to choose between his ambition and the girl he’s falling for.
