In a beastly world where magic intertwines with royal courts, Avery—a feline beastwoman orphan—has been betrothed to Prince Regulus since childhood. Regulus breaks their engagement, mocks her, and has an affair with a fox dancer. Desperate to cure her heat disorder, Avery, fueled by alcohol, mistakenly enters the forbidden nine-tiered bedchamber and meets Caspian, the lion king rumored to have killed his queen. Mistaking him for a physician, she begs for help, leading to a night of debauchery that awakens her heat. When she removes her blindfold, she realizes Caspian is Regulus's father, who blackmails her into an engagement. At their banquet, Avery faces humiliation from Regulus and his mistress, but Caspian proclaims her his future queen, providing protection. Despite his care, Avery fears for her safety and that of their unborn child. As she plans her escape, the truth unfolds, and after overcoming life-and-death challenges, they confront their true feelings, while Regulus and Isabella face the consequences of their actions.
