God of Pain by Rina Kent

I made a terrible mistake. Being a mafia princess, I knew my fate was already decided. But I went ahead and longed for the wrong one. Creighton King is bad news with a gorgeous exterior. He’s silent, brooding, and obviously emotionally unavailable. So I thought it was over. Until he awakens a beast inside me. My name is Annika Volkov, and I’m Creighton's worst enemy. He won’t stop until he breaks me. Or I break him. This book can be listened to on its own.
