Black Hearts by Candace Wondrak

I’ve fallen in love with my monsters, and only they can save me now.
Daddy kept me locked away my entire life. He molded me, shaped me into what he wanted me to be: a naive, innocent slave to his will. His word was supposed to be law.
And then I met Markus, and everything changed.
I’ve grown to love my monsters. I need them. They complete me in ways I never could’ve imagined, made me feel alive and showed me just how much of a liar Daddy is.
As it turns out, the worst monster of them all is the one I was raised by, and if he can’t have me, no one can. But I’m not the same girl I was in the beginning. I want to fight back.
The innocent girl I used to be is dead. The darkness made sure of it.
