Ria is safe and sound from her potential kidnappers thanks to Asisi's swift rescue, but she's left with more questions than ever about the Guardian Knight. What's the story behind his scar-riddled back? And why does everyone act so strangely when she tries to bring it up? Ria's determined to get to the bottom of things-even if it takes every last one of her princess charms!
