Betraying Korth by Mary Mecham

Traitorous spies don’t deserve happily ever afters.

Dahlia has always known her life would end at the bottom of a hangman’s noose. But treason seems a small price to pay if it meant a chance to free her people from the iron grip of their tyrannical king. Dahlia can’t fail the rebellion now.
Dahlia’s time playing the role of obedient handmaiden to Odette, the king’s entitled daughter, comes to an end when Odette is sent to marry her betrothed, and Dahlia strikes without mercy. After a swift mutiny en route to Haven Harbor, she forces the king’s daughter to trade places with her and upon arrival, masquerades in her mistress’s place.
If she can ensure Haven Harbor’s loyalty to her rebellion, the king’s oppressive reign could end. But the princess’s fiancé, Korth, isn’t the man she expected, and her loyalties become torn as she begins to fall for him. Continuing the façade will force Dahlia to betray Korth, but to reveal the truth spells her own treasonous demise.
Is a life of lies better than no life at all?

Betraying Korth is the third book in the Legends of Neverland series but can also be read as a stand-alone novel.
