In a dark, gothic city, a centuries-old battle rages in the shadows. This ancient war is fought between two immortal species: the aristocratic vampires and the brutal lycans, an offshoot of werewolves. Selene, a dedicated and skilled vampire warrior known as a Death Dealer, takes pride in her role of hunting and killing the lycans who are seen as a plague to her kind. One night, the balance of power begins to shift when Selene uncovers a lycan plot to capture a seemingly unremarkable human named Michael Corvin. Sensing a deeper conspiracy at work, her instincts tell her that Michael is more important than he appears and that his capture could be the key to ending the eternal conflict.

Suspicion and curiosity drive Selene to defy the orders of Kraven, the second-in-command of her coven and a scheming vampire with his own agenda. She decides to protect Michael and discover why he is so valuable to the lycans. As Selene becomes entangled with Michael, she is haunted by visions of a time long past, suggesting a connection between Michael, the vampires, and the lycans that could drastically alter the course of the war. Her inquiry puts her at odds with her own kind and leads her to unearth long-hidden secrets that challenge everything she has known about the ancient feud and her own heritage.
