Claudia's engagement to Prince Sylvester is now official, but our heroine hardly has time to celebrate.

If Claudia hopes to stand beside Sylvester and take command of the aristocracy, she simply has to comply. But just as she vows to fulfill her duty, animals begin to go missing around her, and swirling speculations complicate her rise to power!
