Olivier is a devout adherent to a little-known sect of Christianity. In the Middle Ages, he traded his soul for eternal life in order to protect the remnants of his religion and culture. Sophie is a modern day college professor in Chicago working toward her doctorate - and the reincarnation of Olivier's lost love from almost one thousand years ago. When Olivier turns Sophie into a vampire mere weeks before Christmas, he expects her to be thrilled and accept her destiny, but despite her powerful sexual attraction to him, the intrepid Sophie has other plans. She turns her two best friends into vampires, donates all her old clothing to homeless shelters, and debates whether vampires can be vegetarians. Her friends insist that vampires can take whatever they want whenever they want, but Sophie would rather continue in her quiet life, teaching young religious studies students about heresies, than steal jewels and listen to Olivier recite poetry all day. But when she and her friends accidentally get stuck in the fairy realm - and free a death fairy from what was supposed to be his eternal prison - Sophie must go on a quest and set everything right before Christmas Eve is over. For this, she needs the help of Olivier, for only he knows the secrets of the midnight work. It seems that the more Sophie fights her attraction to him, the stronger her attraction grows - maybe they really are meant to be together forever! But only if they can stop Ankou the death fairy from destroying humankind first.
