Silent Surrender (The Royal Heirs #1)
Lizabeth Scott

When his father tasks him with a very delicate and secret mission, Creston cringes at the thought of swooping in to save some needy clueless princess. But he knows by the glint in his father’s eyes it’s not a request, and no one refuses the King. Creston will go, but he’ll do it his way.
Lis MacKenzie isn’t someone who can be ordered around. She’s strong and independent. She’s had to be. So why is she allowing Prince Creston to whisk her away to a far-off land where nothing makes sense? She has no interest in meeting some king who claims to be her father.
So why is she going, and why is she staying when it could cost her the one man who sees her as a desirable woman? Lis knows how to fight for what she wants, she’s had to do it all her life, but this time the lines are blurred.
Loving Lis comes with responsibilities Creston’s run from all his life. Now he must decide if going from spare to heir is what’s best for not only Lis, but for an entire country.
