Summary:

Shadow Viguie used to be a cold, heartless vampire whose vengeance was feared throughout the world. Then her husband cheated on her and she joined a mostly human organization called the Black Roses. She and her 'sisters' Lunnette and Anfanasia make up an elite fighting force used to cleanly cut the unwanted from America's high society.

Their target this time is the president's son, Eric Pearson. The mission: seduce him to the dark side. But what can Shadow do when her heart has been broken too many times and she's on the verge of falling back to the person she was so long ago? And William, her husband-who'd give a divorce to someone when the marriage date was too long ago to make sense for a couple of teenagers- show up to try and get her back. What can a girl- or vampire- do?
