Vivatera by Candace J Thomas

Naomi never understood what the star-shaped scar on her neck meant, only that she was told her to keep it covered.

But on this day, the prince of Parbraven has arrived with his caravan. There, in the back of his carriage sits a woman, ethereal and wind-swept, silently observing the awestruck crowd—a woman with the same mark on her neck. Within that moment, time slows and the significance of what she is seeing focuses to a point. She is not alone, someone else is marked. As Naomi hurries to understand this connection to a stranger, she is whisked away from the discovery of her past, kidnapped by Reynolds Fairborne, a man who knows her secret and has vowed to keep her safe.
