Eileen lives a pleasantly normal life. She works in Public Relations in the family business, she earns a good salary, and is crazy about her Huskie and the two friends that she has had since childhood. Furthermore, she has just graduated in teaching, and been offered a great job in London on an educational project: the perfect opportunity to escape from the clutches of her father Mikhail, a man she doesn't love and whom she blames for her mother's death. What she cannot imagine is that that very night, Caleb, a tormented man, a Vanirio, an immortal being created by the Scandinavian Gods, who has travelled to Barcelona to find the strange organisation which is kidnapping and killing all those like him, will kidnap her and drag her into a world full of myths, magic, clans, blood and fangs. There is no more than a bite between love and death.
