Sixty years ago, to end a catastrophic war, the Oracle Olga forged her own flesh and soul into twelve Embers of Grace and gave them to mortals. Now, she returns with hollow eyes to reclaim her power. With each shard she retrieves, she exposes a family's deepest, darkest betrayals. Her journey takes her from a treacherous ducal house, to the Wilson family who trade in years of life for their healing arts, and finally to the frozen North, besieged by the undead. On this bloody path of reckoning, the only one who stands by her side is Commander Samuel Wilson, a mortal who dares to defy her prophecies of his own death. As a goddess takes back her gifts, the laws and fate of the mortal world are about to be rewritten forever.
