By stopping Zayd, Cordelia has earned the title of “The Lion Saint” and received an engagement to Prince Leonhart. But her future sister-in-law Femina won't stand for it. She demands Cordelia refuse the position and her betrothal! Her tantrum is so childish and over the top that it's honestly kind of cute, but could this be a warning sign of how rocky a road waits ahead for Cordelia and her prince?
