Since the day she was born, Reign has felt the pull-a thread of magic tugging at her soul, drawing her toward something. Someone.

She always believed it led to the devil her mother signed a contract with before she was born. The contract had changed her-born into the world with horns, fangs, scarlet skin, and a tail-like the devil who signed it. The one she calls her father. Finding him gave her hope during the long years of torment from her noble family, who despised her for what she was.

Now, she's following the thread, convinced it will lead her to the only being who might have answers. But her grandfather has other plans. A powerful wizard with dangerous ambitions, he sees her ties to the Nine Circles of Hell as his key to ultimate power. And he's willing to sacrifice her soul to get it.

But at the end of the thread, Reign doesn't find her father. She finds Leander, Prince of the Fire Circle of Hell, a devil as infamous as he is irresistible. Bound to her by a hidden clause in the contract, Leander is not just another devil-he is her soul mate. She should hate him, but for the first time in her life, he is someone offering her a choice in her destiny.

Can she ever be free of her grandfather? Can she trust a bond she never asked for? Should she seek out the devil who created her and demand answers?

The truth may break her-or it might set her free.
