It is about this village of girls high up in the mountains who are suddenly told they need to join this Princess Academy so they they can learn to be a lady who would be suitable for the Prince to marry. These girls are quarry girls who know nothing but the stone they help produce. Well, all except Miri, our main character, who has been told by her father not to be in the quarry and he never tells her why. So being forced to go to this Princess Academy gives her a change of pace and a chance to be with the girls that seem to have ostracized her. The headmistress of this academy is a cruel one where if a girl speaks without having been spoken to first she gets her hands whipped and sent into a dark, rat infested closet for hours on end.
Miri slowly gains friends and enemies throughout her time there while she studies. She learns a lot, not only to be able to read or curtsy, but about economics and histories that can help her little village that is isolated from everywhere else. Over the course of the book she finds purpose and a power she didn't know she had.
This book is an award winning book for a reason. It was very well written with good scenery and setting. The characters, side characters and all, had depth to them and improved as the story went on. My only problem is the slowness of the book toward the beginning and early middle. Simply studying and figuring out this new power of her's took a long time where it felt like nothing was actually going on. It very much picked up toward the end as bandits suddenly lay siege on the academy, so far away from their own village and families. That part was most fun. It even had a good bad guy, with good foreshadowing so then it wasn't something completely out of the blue that happened.
I enjoyed the book and agree that young girls (and boys) would enjoy this as they would Ella Enchanted. It would be a book I would offer as an introduction to most fantasy books for young people if they were hesitant toward dragons and sword fights.
