Following Hearts

Rose Lovelle, Princess of Adaia, is caught between a rock and a hard place.
The rock being her arranged engagement with the Prince of the neighboring kingdom -- a handsome charmer by the name of Balthazar Blade -- and the hard place being her secret relationship with the palace stable boy. What's a Princess to do?
Ferdinand Lovelle, Prince of Adaia, finds himself in a similar predicament.
Upon the arrival of Prince Balthazar, he can't ignore the implications of his growing attraction, and he knows that his feelings must be set aside for the sake of Adaia. But as time passes, he finds it harder and harder to resist the calling of his heart.
With their older sister's coronation rapidly approaching, Rose and Ferdinand must answer one question: Will they honor their kingdom, or follow their hearts?
