Popular Gossip Girl character Jenny Humphrey in leaving Contance Billard to attend Waverly Academy, an elite boarding school in New York horse country where glamorous rich kids don't let the rules get in the way of an excellent time.Determined to leave her Manhattan past behind her, Jenny sets off to Waverly with big plans of reinventing herself. She'll be a goddess -- she's a sophisticated city girl, after all! -- and will find a boy who can properly worship her. But that's going to be a little tricky since her self-absorbed new roommates, Callie Vernon and Brett Messerschmidt, aren't exactly there to help -- unless there's something in it for them.
Hot guys, new intrigue, and delicious gossip add up to more trouble than ever for Jenny. But if getting caught with boys and going up against the Disciplinary Committee is what it takes, Jenny's ready -- she'll do all that and more to become The It Girl.
