Taken By the Dragon Prince by Kiersten Fay

Prince Khalstorm Belmont lost everything the day his kingdom was destroyed. Imprisoned for a crime he never committed, he dreams of exacting his revenge against the witch responsible, a treacherous beauty who once tempted him beyond reason, only to betray him in the end. When Khalstorm captures her, he discovers his feelings for her are as strong as ever, leading him torn between his hunger for vengeance and his hunger for her.
Celeste Songbird both feared and longed for the day Khalstorm found her. No longer resembling the man she once loved, he is filled with rage and regret…and on a mission for her blood. Temporarily stripped of her powers, her life is at his mercy. Can she break through his ice-cold heart before all is lost?
