Princess Knight is a fast-paced tale of a heroic princess who can beat any man at fencing, yet is delicate and graceful enough to catch the eye of Prince Charming.

A mischief-making angel’s prank goes too far when the newborn princess of Silverland ends up with two hearts—one male and one female. Since the laws of Silverland only allow a male heir to ascend the throne, Princess Sapphire is raised as a prince. But will the avaricious Duke Duralumin discover Sapphire’s true nature and snatch the crown for his own son?
