The Fallen King--Book #4 (The Bellum Sisters series)

Four sisters. Four fates.
Banished demon king Alrik Demuzi has lost everything: the life he knew, the only brother he ever had, the woman he cared for, and his kingdom. Now he has no one and nothing. But, the blackened-skinned demon has purpose. He will get vengance on the creature who cursed him to be an evil, ravaged creature incapable of knowing real love or compassion - his very own mother. She's out there in the rift, gathering forces and amassing an army; for what, he cannot say.
When an ancient seer tells Alrik that a mere human witch by the name of Abbigail Krenshaw is the key to saving himself and killing his mother, Alrik steals the woman he needs. Only, as he soon begins to learn, Abbigail is uncooperative to his needs and the longer he's around her, training her, preparing her for her fate, he finds himself longing for her in other ways. In the ways a man will with the woman he craves.
Strong, resilient, and resourceful, beautiful Abbigail worms her way into Alrik's blackened heart. Now he can't decide whether he wants to keep her close or carry through with his deadly plans. Either way, it means death for one of them.
