That is until an Emperor Vampire named Lord Lucian Dascălu appeared one night and informed Bianca that she was his heir. To ensure that his bloodline would continue, Lucian bites Bianca, thus transferring the curse to her. But Sebastian refuses to go through life without Bianca and voluntarily chooses to be damned with her. The lovers find a witch's book that holds the key to ending the curse, but they must run from an army of Jesuit Priests who are bent on sending them to hell.
