Five years after Blaze was maimed by Cyrus Chimola, a powerful vampire with a penchant for torture, he’s still trying to pick up the pieces of his shattered life. As a genetically engineered mercenary with the ability to bend fire to his will and to see in infrared, Blaze’s mission is to protect what’s left of humanity. When Chimola and his crew return to the Bronx gunning for Blaze’s blood, Blaze is forced to face the demons of his past. Hell-bent on revenge, he seeks the help of Valerie Medeiros, an NYPD detective who manages to steal his heart and save his life in more ways than one. Motivated by her sister’s gruesome death, Valerie has made it her life’s goal to bury every vampire in the ground where they belong. When she brings in Blaze Knight for suspected murder, she discovers he’s not only innocent, he isn't a man at all—he's a half-vampire hybrid working with a band of brothers for the U.S. military. Valerie has a hard time trusting anything with fangs, yet she quickly falls headlong into Blaze’s life, a life full of darkness and horror she can’t even begin to fathom. The bodies are stacking up, but Valerie can’t seem to let go of this hybrid, a beautiful monster filled with pain, rage, and passion unlike anything she's ever known. In a world where the line between good and evil is blurred, Blaze and Valerie will find danger at every turn, risking everything they’ve come to know and love, including one another. less
