New York City is in the grasp of a deadly, unseen enemy. At least unseen by normal society. Lieutenant Jess Vandermire, New York City police officer, is uniquely specialized to recognize and fight this threat. It's her job to forge a black ops team, an assortment of men and women who wouldn't be considered for the job under normal circumstances. But these aren't normal circumstances. The team has to be tough and, if need be, expendable. Jess understands what she's fighting and what's at stake. For her, it's all about retribution until ex-cop John Brittain is recruited to her team. Suddenly, her priorities aren't quite so easily definable. John Brittain has a chip on his shoulder and is as tough as they come. But is he ready for the whole truth? That combating "super" vampires whose primal need for blood and the addictive drug "Sunshine" is only the beginning of their problems? And when Jess tells him the truth about herself, will he stay and fight or will he turn against her and not only threaten their lives but destroy the fragile relationship developing between them?
