The Alchemy of Forever (2012):
While the love story with Noah is nice enough, it's the other stuff—dealing with high school, being answerable to loving parents, seeing the consequences of her actions (rather than just moving on*), and finding that she has both more freedom (because of escaping Cyrus) and less freedom (she's underage) than she's used to—that's closer to the heart of her journey.
