She wears the face of a noble but bears the heart of a maid—and a secret that could cost her everything.

Katlya has always been more than a maid to Laird Normand's daughter. Inseparable and strikingly alike, they're often called "sisters." Rumors swirl through the clan that Katlya is the Laird's own blood, a scandalous possibility that only fuels his cruel treatment of her.

Driven by vengeance, the feared pirate captain Duncan Campbell returns to the Highlands with a single mission: to destroy Laird Normand by kidnapping his beloved daughter. But in a twist of fate, he abducts Katlya instead.

When Duncan reveals his deadly plan, Katlya realizes that the truth of her identity could seal her doom. Trapped aboard a pirate ship, she must navigate a web of deception. Can she help Duncan achieve his revenge without revealing who she truly is, or is masquerading as a noble lady her only hope for survival?

As stormy seas and dark hearts collide, Katlya faces an impossible choice that could change all their lives forever.
