The Little Saint and the Grand Duke of the North

Everyone knows Duke Windzorice is a cold, powerful man, but for the young saint Lilliette, he's a kind adult and just the person to save her from the Temple's abuse! After healing his eyes, Lilliette is granted a home at Windzorice Castle, but the Temple's not willing to let her go. That's when the duke comes up with a foolproof plan to keep her by his side... They'll say she's his daughter! Can this fake family vanquish the Temple and live in peace? Or will the little saint suffer once more?
