Dishonorable - Amado Brothers, #1

Sofia I didn't know Raphael Amado when he turned up on our doorstep demanding restitution for an old debt. My grandfather knew him well, though, and he quickly conceded.  That restitution? Me. Six months later, on my eighteenth birthday, Raphael came to claim me.  He stole me from my home, taking me to his Tuscan estate, where from the crumbling chapel to the destroyed vineyard to that dark cellar, the past stalked him like a shadow. Even the walls held secrets here and I'd need to uncover them all to survive. Because taking me was only the beginning of his plan.  Raphael Sofia was the sacrifice to pay for her grandfather's sins.  She accused me of being the devil.
And she's right. But the truth was, he betrayed her.  And when the time came to promise to love, cherish, and obey she spoke the words that would seal her fate. I do. We have a common enemy, though, my unwilling bride and I. But even the devil protects what's his. And she's mine. She just doesn't yet know how much protecting she needs.
