The Secret Princess

from fictiondb:

FROM PLAIN JANE TO PRINCESS?

Amy Scott had been more at home sitting in her small-town bookshop than she'd ever be on the imperial throne of Lufthania. But according to heart-stoppingly-handsome Crown Prince Wilhelm, that is exactly where the striking redhead belonged, on his throne.

Then just as Amy, uh, Princess Amelia, was getting the hang of the princess thing -- and oh-so-much closer to her regal tutor -- Prince Will wanted to bow out of her life. It seemed he had a personal rule about falling in love, especially with his new sovereign.
