Basically, your standard "knight in shining armor saves the woman from the castle" fairy tale. Except the woman is a shapeshifting creature that society perceives as a monster. And the knight in shining armor is actually two guys- one is her adopted human son with draconic blood and the other is the human guy whose been hopelessly in love with her for something like twenty years. And the castle in question has been loaned to a royally sanctioned operation which harvests the miracle blood from her species.
