Savage Prince by Ivy Thorn

I was named after the goddess of war. I’m no one’s sacrifice.
Dean Blackmoor says I’m his. But I’ve got other ideas. After finding out that I’ve chosen the winner of a game I didn’t even know I was playing, I’m determined to make sure that this doesn’t go the way my captors planned.
Any of them.
After years of being obsessed with me, Cayde St. Vincent has decided to concede, and let Dean claim his victory. But I know he still wants me, and I intend to exploit that in any way I possibly can—up to and including finding my way into his bed.
The shadows surrounding Blackmoor House are dark, and there’s plenty of other dangers lurking there, waiting to make me pay for sins that aren’t even mine. But I’m not afraid.
They thought I belonged to them. But I’m going to show them just how wrong they are.
They’re playing my game now.
