Suddenly, Trey finds himself living in a luxury penthouse at the heart of a strange and sinister empire built on the powers of the Netherworld - vampires, demons, sorcerers, and djinn.

Trey is training night and day to control the newly discovered power lurking inside him. Now, demons are closing in on every side, and the most psychopathic bloodsucker to rock the Netherworld wants to destroy him.

A few short months ago, Trey Laporte learned the news that would change him forever: He is a werewolf, and the evil vampire Caliban wants him dead. The threat becomes real when Caliban attacks Trey's mentor, Lucien Charron, and leaves him fighting for his life. Gwendolin, a wicked sorceress, holds the only key to saving Lucien. Together, Trey and Lucien's beautiful daughter, Alexa, must enter the Netherworld to defeat her. The pressure for Trey is great, Alexa is counting on him to save her father. But, when Trey and Alexa find themselves trapped and surrounded by demons, can Trey use his werewolf strength to save them both?

Trey Laporte had been told he was the only one. It was a lie. But, some secrets he would have been better off not knowing. Trey, the last hereditary werewolf, has found his pack, and they're vicious, bloodthirsty, and truly wild. All Trey wants is to go home, but having learned more about his Wolfen nature, he has decided, for the safety of his friends, to never return. Back in London, Alexis uses her magic to track down the Necrotroph that is intent on infiltrating her father, Lucien's, organization. But, while Alexis is focused on the outside threat, Lucien is battling with his own darkness. His evil brother Caliban's savage bite and the poison left behind have reawakened Lucien's vampire instincts, turning every night into a battle.

After his disastrous trip to Alaska, werewolf Trey Laporte returns to London to discover that his vampire guardian Lucian is missing, and Lucian's daughter Alexa, Trey's long time crush, has entered the demon realm to rescue a kidnapped friend. Using Lucian's resources, Trey quickly finds a guide to lead him and sets off on a rescue mission of his own. But, when he discovers that his "trusty" demon guide has betrayed them all and Alexa has been captured, Trey is faced with a terrible choice: Compete in the gladitorial Demon Games against unbeatable foes for the amusement of the Demon Lord Moloch or watch Alexa die.
