From New York Times and USA Today bestselling author Skye Warren comes the next installment in her North Security series.

Fransisco Castille, the exiled Duke of Linares, knows his duty. Even in modern times, the line must continue. So he'll marry and produce an heir.

Yes, a wife will fit into his well-ordered life.

Instead he ends up with the brilliant pianist Isabella. Strong. Spirited. And highly disobedient. She rebels against every custom and every rule, threatening his careful balance.

Fransisco never backs away from a challenge.

Isabella never bows down to anyone.

This scorching hot battle of wills may leave both of them broken.
