Thanks to her efforts in foiling Algard's plots, Anisphia's right to the throne is restored, and the former oddball princess is now future queen of the land. All of a sudden, it's like she's a different person--working tirelessly on government affairs to prepare to lead the kingdom and even throwing her beloved magical studies out the window. Euphie wants nothing more than to relieve Anis of her burdens, but she fears she can't do much to help...until she chances upon a mysterious spirit covenantor!
