Books like A Hidden Magic

Once upon a time there was a very nice but very plain princess named Jennifer, who, following proper fairy-tale protocol, fell for a very handsome but very conceited prince named Alexander. When Alexander offends a powerful witch, it falls to Jennifer to save him. In the course of doing so, she meets a wizard and soon wonders if she’s such a proper fairy-tale princess after all—a good little princess would love Alexander, but does she?
