Forbidden Vow by Lilith Vincent

Lucy is the only woman I love. The only heart I cherish. But she can never be mine.

Life is danger, and life is pain. I learned that lesson at twelve years of age when my father and sister perished in flames. Lucy and I were the only survivors, she an abandoned little girl with pain in her eyes, tears on her cheeks, and steel in her heart.
I couldn’t lose her, so I lied about who we were, without knowing the terrible price we’d pay. Lucy and I became Barones, children of one of the wealthiest and most sinister families in Malus. I love Lucy more than anyone in the world, but I led her unwittingly into danger.
Our new family treads a dark and violent path, strewn with bullets and blood. Our true identity is a deadly secret. To protect my beautiful Lucy, I must walk the same path as our parents. To save her from a violent fate, I must arrange her marriage to someone else.
But seeing Lucy with another man’s ring on her finger unlocks feral instincts inside me. My desire for her is going to tear our lives apart, because I’m about to do something dangerous, reckless, and utterly forbidden.
I’m going to make Lucy mine.
