Analisa Still has just found out that everything she thought she knew about her life was a lie. To make matters worse, her parents have taken her to a compound for training. Total strangers seem to know more about who she is, what she is, and what she was born to do than she does. And someone at the compound wants her dead. When the compound is attacked and the world overrun with vampires (and something else), Ana is forced to team up with the unlikeliest of allies. Thinking her betrothed is dead, Ana soon falls in love with one of her vampire comrades all while vowing to kill the vampires that killed her sister.
