Dulcinea Macgregor Craven is the only child of a wealthy English viscount. She is also a natural witch, one of a long line of Macgregor witches on her mother's side. When her parents are killed in a carriage accident, Dulcie doesn't think her life can get much worse. Then an old childhood friend returns to the country a little bit differently than he left and vows that nothing will stop him from possessing her and her magic.

In a desperate attempt to save her life, Dulcie summons a trio of vampires called The Righteous to her aid. With the help of The Righteous and four human friends, Dulcie attempts to thwart her enemy's plans to capture her and use her magic for his own evil purposes.

Even as she falls in love for the first time, Dulcie realizes that she may have to make the ultimate sacrifice in order to save the world.
