Convicted of treason, Wulfgar, Earl of Glyndwr, was once a favored Norman knight of King William the Conqueror. Sold into slavery for his crimes, Wulfgar is determined to have his honor restored and vows revenge on those who conspired for his downfall. But once Wulfgar belongs to Ariana, he finds there is nothing he will not do to protect her. She holds his heart in her hands and this silken cord is stronger than any chains. Once his betrothed, Princess Ariana of Wales has come to the slave auction to buy Wulfgar, a man she believes betrayed his king. Only Wulfgar knows how to free her young brother from the cruel ruler who has taken Wulfgar's place at Castle Cynan. But she is unprepared for the darkly handsome warrior who kindles a passion within her that threatens the lives of her people and her own soul.
