Corrupt Vow by Eva Ashwood

I’ll do anything to protect them… even if it means walking away.
The Voronin brothers didn’t just save my life. They showed me what it’s like to be truly cared for, to be a part of an unbreakable bond. Which is why I have to do this.
Because even though I never meant for it to happen, I’m falling for all three of them. Malice, Victor, and Ransom each own a piece of my heart, and the thought of what X could do to them makes me feel sick.
So if it keeps them safe, I’ll walk through the very gates of hell. I’ll sign my life over to a man who has a sick fascination with me and a woman who sees me as a tool to manipulate.
Once, I thought the brothers were monsters… but I’m only just starting to understand who the real monsters are.
