An ancient evil. An unholy alliance. An eternal love. William Dark is a monster-a vampire who feeds on blood and fear. He is exactly what Savannah Daniels needs. A year ago, Savannah's twin brother and his wife were brutally murdered. Savannah swore a vow of vengeance against the man, the beast, that killed him. A beast that is now after her. Savannah needs William's help in order to keep her vow. She must convince him to transform her, to give her the kiss of the vampire, so that she will be strong enough to defeat the killer that is on her trail. Savannah and William enter into an unholy alliance: He will transform her and see that she receives her justice. In return, she must be his companion, his mate, for eternity. But Savannah soon realizes that there is more at stake than just her life. Because once she tastes William's kiss, she knows that she may be in jeopardy of losing her heart as well. And she will have to put all of her trust, all of her faith, into the hands of a man who lost his soul centuries ago.
