Her Wicked Promise by Persephone Black

Thirty more days. Ten million dollars. A bargain I can’t resist…and a beast I can’t forget.
I told myself I’d never return.

But my sister’s life is on the line, and Eva Novak knows it. She drags me back into her world with an offer I can’t afford to refuse.
Forbidden fantasies are waiting in her eyes, in her hands, in the ways she claims me. And she seems to be changing. Softening. Blooming around the thorns.
Every wicked promise she whispers leaves me craving the one thing I should fear the most…
Belonging to her completely.
But loving her doesn’t just risk my heart. It risks my family. It risks my life.
I made a deal with the devil. Now I need to decide if saving her soul is worth damning mine.
