Warlocks of Aria. An ancient Earthling tribe that is all but extinct. Two brothers. Demon Sha and Lucian Sha. Once estranged now unite to form a new order. Mia Ravens, a mere powerless human, a scion of the Arian tribe, decendent of her scion ancestors, is the only once who make it all happen. Cat will have to set aside her own differences, her own desires, to bring together two equally opposing forces in order to battle against a new threat.
For those of you who have read The Devil is my Mother series, this is William, Death's story.
