A young visitor from a neighboring dukedom insists that Elianna—the "Bibliophile Princess" betrothed to Prince Christopher—step aside for a woman who has a long history with the prince, compounding an issue that Elianna continues to struggle with: the possibility of the prince one day needing to form a harem. The situation highlights how little she is aware of current events outside her books, and how challenging her future royal obligations may be. Meanwhile, Christopher is busy with his own official duties, leaving Elianna feeling isolated and alone. Torn between her desires and her duty, can she still go through with this marriage? And can she navigate these issues before another proactive rival takes her down?
