The Devil's Thorn by Kyrina K

The devil craved control, but she became the one thing he couldn't tame.

I didn't mean to fall for him. Rafael Romanov was supposed to be a name on a list, a stepping stone to the answers buried in my past. The truth behind my family's death. Instead he became my darkest temptation. A devil cloaked in shadows and sins, pulling me into a world I'd swore I'd destroy. But Rafael isn't just a man, he's a monster with secrets that could shatter me. A predator who's been watching. Waiting...
And now, I don't know if I'm his obsession or his prey. One thing is certain, the closer I get to the truth, the more dangerous he becomes.

And when this game ends, only one of us will walk away.
