Over the past few weeks, Cassie Dean has found herself reliving many of the scenes she had written in her vampire book series. Her fictional vampire hero, Aithen, has come to life in Ethan McCall, a real-life vampire working for the FBI. Her feelings for him have grown passionately and she finally knows his love for her is true. But now another vampire, the villainous Erik Locke, has abducted the greatest hero in Cassie's life: her father. In order to save him, Erik demands she take his place, but doing so will bring her a fate worse than death.

Ethan McCall is willing to do anything to stop Erik from making Cassie his vampire bride. However, things are more complicated than he'd expected, and the coming storm is bigger than he can handle alone. To save both, he must put his trust in unlikely allies to discover a way to bring Erik Locke's reign of terror to an end, once and for all.

An ancient amulet holds the answers all three of them desire, tying their fates together. Each decision they make will determine their destiny; one wrong move and they could find themselves choosing the sunset.
