Daughter Of The Sun by Lonnie Ezell

Since the Sundering, all use of the Breath has been outlawed. The Overlord and his family have destroyed all who could wield that mighty power. Now, the Overlord's own son needs that outlawed power to unseat his father. Having spent her entire life trying to stay unnoticed, Elena is forced to come to grips with the Breath's curse when her only child is ripped away from her. A pawn in the game between the Duke and his father, she must find a way to rescue her daughter and remain free of their manipulative grasp. When she does, her entire world collapses around her, and she realizes just how dangerous this game is. As she struggles to out maneuver the Overlord, the Duke, and their supernatural allies, Elena must find a way to defeat them both. If she cannot, the entire world will pay the price.
