Vampire's Tribute

A vampire-themed Beauty and the Beast: When Isobel's neighbors sacrifice her sister as tribute to the mysterious demon who dwells in the nearby castle, Isobel offers herself as a substitute. Her new master, Reynard, proves very different from what she expected. As he preys on her body and ravishes her soul, she finds herself falling in love with a creature who isn't even human. How can she endure the heartbreak when Reynard wants to send her home for her own good? A thousand years later, a descendant of Isobel's sister travels to England to delve into her family's history…and discovers that the ruined castle on the hill is not totally abandoned.
