The Bastard by S.M. LaViolette

His was a face that women carried with them into their nightmares, not their fantasies…
John Fielding is not a gentleman. His brutal past has left him scarred, mind and body. But the scars are a valuable reminder of what’s truly important. Revenge. And John will have his vengeance on the man who abandoned him when he was just a child. In fact, he’ll make the entire bloodline pay for the sins of his father. No one can stop him. Except maybe Cordelia. She’s everything John is not—kind and generous and loving. A good person. She deserves so much better than living in the shadow of her cruel sister. And she certainly deserves better than a beast like him. But that doesn’t stop John from wanting her. Cordelia shines a light into the darkest corners of his soul, making him question what he’s been living for all these years.

Now, he’s only sure of one thing.
Her love could save him…but only if his quest for revenge doesn’t destroy them both first
