What is true evil? How do you fight it? Since she was little, Lada wanted to be part of the Order of Fennarin, one of the warrior-monks who are the last bastion in a war against the demons and insurgents that threaten her island home. Yet to achieve her dream, Lada turned blood traitor, her decision leading to the death and exile of her family. Her betrayal comes to haunt her now, ten years later, when her elders demand that she oversees her brother Ailas's trial. Lada feared him lost forever, thanks to his covenant with demons, which makes him anathema to her and her order. Will she deny her blood and uphold the order that's become her family? Or will she listen to the whispers of the demons? After all, they might just be telling the truth - though a truth that may make her question everything, even the organisation to which she's entrusted her very soul.
