Lady Hope is an ancestor of the high king of Ireland and has a spirited soul that is set on adventure before she must settle into an arranged marriage. Disguised as a lad and accompanied by her faithful, though cowardly dog Lady Gwyneth, Hope sets out on her journey. Only to discover that adventure can be dangerous… to the heart.

Colin of Shanekill can charm any woman into his bed and conquer any warrior in battle. But true love has eluded him, or has he eluded love? While on a mission for the Irish Devil to find Lady Hope a spoiled aristocrat who ran away from responsibility, he comes across a young lad, Harold, in dire need of help. He takes charge of him, seeing to his care and teaches him what it takes to become a man and what it takes to charm a woman.

Once identities are discovered can the charmer tempt the impetuous Lady Hope or will she teach him to finally love?
