The Lady of the Forest (Knights of Destiny #1)
Barbara Bettis

Henry of Chauvere has found the one lady he wants for his own, never mind she’s tied him hand and foot. When he learns the king has ordered her to wed Stonehill’s ruthless new master, he insists Kate seek haven with his sister. But she won’t desert her friends. Henry vows to solve her problem, provided he catches a traitor before the threat from Kate’s past catches her.
When a daring rescue compels Henry and Kate to join forces, their attraction grows into love. If only duty didn’t drive them apart.
