Readers encounter a cast of local characters and outsiders, including Susan Norton and Father Callahan, as they gradually confront the supernatural menace that transforms the townspeople into the undead. The narrative also includes meta-commentary on vampire fiction and the novel's structure, comparing it to Bram Stoker's Dracula and explaining how the modern setting aids the supernatural forces.
