I loved Austenland and thought it was about time I tried something else by Shannon Hale. I didn't love Princess Academy in the same way, but I liked it pretty well. My favorite thing about it is how the main character learns that her assumptions about people are usually wrong. It's an entertaining story with good messages, just like a kids' novel ought to be.
Shannon Hale is a better writer than most of the LDS authors out there these days. I'll be reading more of her stuff.
