HAUNTING ADELINE by H.D. Carlton

"The Diamond. Death walks alongside me but the reaper is no match for me. I'm trapped in a world full of monsters dressed as men, and those who aren't as they seem. They won't keep me forever. I no longer recognize the person I've become. And I'm fighting to find my way back to the beast who hunts me in the night. They call me a diamond. But they've only created an angel of death. The Hunter. I was born a predator, with ruthlessness ingrained in my bones, when what's mine is stolen from me in the night, like a diamond hidden within a fortress. I find that I can no longer contain the beast. Blood will paint the ground as I tear apart this world to find her, and bring her back to where she belongs. No one will escape my wrath, especially not those who have betrayed me"-
