Haunted by memories from his first days as a vampire, Balthazar has spent hundreds of years alone—without allies, without love. When he emerges from his isolation to help Skye Tierney, a human girl who once attended Evernight Academy, Balthazar has no idea how dangerous it will be. Skye's psychic powers have caught the attention of Redgrave, the cruel master vampire responsible for murdering Balthazar and his family four centuries ago. Having learned of Skye's powers and the remarkable effect her blood has on vampires, he plans to use her for his own evil purposes. As they stand together to fight the evil vampire, Balthazar realizes his lonely world could finally be changed by Skye... just as Redgrave realizes that he can destroy Balthazar once and for all by taking her for his own.
