Devastating and far-reaching chaos spreads fast and Robyn makes it worse. She botched her task, failed her surrogate father, is hunted by Keepers, and now her sister is in danger. Desperate to save her sister, she's persuaded to become a Keeper, turning into the very thing she abhors. She must use her heightened abilities and the ancient sword-relic to kill a Keeper who spreads the chaos. However, killing comes with a wicked price, igniting a lust for delivering death. Devon Hunter is seen as the mythical devil, the monster from whom mothers protect their children. When learning that another human, Robyn, exists, Devon ends his isolation. Robyn is not just any human, but the woman he loved a lifetime ago... the woman who died in his arms. As Keepers move to trap Robyn, he races to find her. Although rescuing Robyn may kill him and prolong the wars, he'll stop at nothing, including unleashing hell-like fury to save her.
