- Complete Monster: Lord Raith, King of the White Court and the head of House Raith, who also appears in White Night, manages to stand out amongst his peers as one of the cruelest White Court vampires. While all the Houses of the White Court feed off of the emotions of their victims to maintain their power, House Raith feeds off of lust. In order to maintain his absolute control over his household, Lord Raith raped and fed off his daughters to make them his slaves and murdered his sons to prevent them from becoming threats. This behavior stopped when Raith killed Harry's mother, who used her death curse to ensure that Raith could no longer feed and gain power. This forced Raith to limit his magic usage and act through mortal intermediaries. When a former employee of his, Arturo, begins to work independently as head of his own porno studio, Raith arranges the murder of several of Arturo’s workers to force Arturo to work for Raith again. Yet these plans take a backseat once he discovers that Harry is the son of the woman who cursed him and that Harry's death would enable him to feed again and regain his former glory. By the end of the novel, Raith has attempted to kill his son Thomas, plans on keeping Harry's Love Interest, Murphy, as a Sex Slave, and intends to rape Inari, his youngest daughter.
