As the eldest daughter of one of the most powerful families, Delphine Hamilton was born with extraordinary powers.
She is the result of generations of experiments to create a witch capable of destroying vampires, permanently. Only Delphine has no interest in being her family's monster. So on the night of her coming of age ceremony, she runs away to the one place her family can't search - vampire territory. Also known as New York City.
Years later, she's etched out a semblance of a life, pretending to be human to stay under the radar alongside her charming roommate, Claude. But when she hears her family has "offered" Fenris, the territory's coven head, a marriage alliance with her younger sister, Delphine knows her time is up. Delphine goes to Fenris with what she thinks is a better offer: she'll share with him the Hamilton's most precious secrets and in return, he will break off the engagement from her sister and keep her under his protection for a year.
While Delphine struggles to keep her magic contained, not everyone is pleased that their coven head has taken a witch under his roof . . . and slowly, bound to a vampire Delphine will come to love . . . and no longer owned by her bloodline, will she alter the balance between witches, vampires, and humans . . . for ever?
