Alone in the dangerous vampire castle, she catches the eye of Lestat, the 9,000-year-old vampire lord. Her rare blood makes her irreplaceable to him. Wracked with regret, Alonso tries every means to win her back, even allying with werewolves to stir up conflict. Torn between her remorseful old flame who brought her endless pain, and the vampire king who cherishes and protects her wholeheartedly, Katia navigates tangled conflicts between humans, vampires and werewolves, and finally makes a choice about love and her own destiny.
