Lady Catherine risks her life to spy on her traitorous husband for her friend, Prince Harry. When her husband is captured and killed, she learns how the King rewards a woman's loyalty. He declares her lands forfeit and threatens to imprison her for her husband's treachery. The only way she can save herself is to wed the man the King has chosen to hold her strategic castle on the Welsh border.

William FitzAlan arrives at Ross Castle, his surcoat still bloody from battle, to claim the traitor's lands. But there is one last price he must pay for them: he must marry the beautiful widow. He cannot help desiring her but can he ever trust her?
