Stanely. Diane. Stella at midnight

Stanley, Diane. Bella at midnight. HarperCollins, 2006 0-06-077573-4//978-0-06-077573-5]
Bella's mother dies in childbirth. Her father who doesn't want to deal with children sends her off to be raised by peasants. Bella is not to be told she is royal. After several plot twists, Bella ends up saving the country from a terrible war. This 278 page book is a great story with a girl main character saving the day (if you can get past trying to call it "Stella by starlight.") She does save the day (or night) at midnight in the starlight.
