For a decade, Vivian Valerius existed as a Void . A wolf lacking vitality, merely a specter in the illustrious halls of the Sun Clan. She withstood the harshness of the elite for Prince Damian's sake, only to face brutal rejection and be labeled a traitor on the night of the Blood Moon. Exiled to the frigid North, she finds herself captured by none other than Dominic Vane, the "Butcher" Alpha of the Shadow Pack, who despises her lineage even more than he does the Sun. Dominic seeks revenge for her father's transgressions. However, the Moon has other plans for them. As Vivian is forced into a life of relentless atonement within the Shadow Citadel, she begins to shed the debilitating "medicine" that kept her subdued. What she experiences isn't an illness but rather an awakening; she is not merely a Void but Astraea,a primordial entity capable of turning iron into ash and reducing kings to dust. Caught between a King intent on breaking her and a Prince eager to exploit her as a power source, Vivian must navigate treacherous ties and an impending conflict. To safeguard her spirit and the hidden heir growing inside her she can no longer remain in hiding. The Sun once obliterated her world, but they are about to discover that nothing endures in the presence of Ash.
