After combat news cameraman Adam Parker covers a Times Square attack by blue-skinned aliens that costs hundreds of lives, the invaders try to kidnap him. Fortunately, the attempt is foiled by a sword-swinging Knight of the Round Table and his witch partner. But when the vampire knight removes his helmet, Adam realizes Sir Baldulf is the father who abandoned him and his mother when he was ten.
Ulf swears he and Opal Cassidy are Adam's only hope of survival. Otherwise the aliens will keep coming after him. Furious, Adam wants nothing to do with either of them -- especially after Opal uses her magic to force him to run from the aliens instead of doing his job.
Opal has been ordered to seduce Adam and transform him into a vampire. Still grieving for a previous partner after more than a decade, the witch wants nothing to do with the handsome, cynical mortal. But orders are orders, so seduction it is.
Despite Adam's bitterness and her grief, the two discover they have red-hot sexual chemistry. As the stakes climb and passion turns to love, Opal and Adam realize that if they don't take a chance on each other, humanity will pay the price.
