Holly might be new, but she already knows who to watch out for: Jess Flynn, the most popular girl in year nine. Holly's best friend back in Melbourne, Calypso, says Jess is a liar, a shoplifter and a boyfriend-stealer. Calypso wants revenge for her ex-friend's betrayal, and Holly's only too happy to oblige. But it's not proving easy to follow Calypso's plan and catch Jess out. And then there's the fact that as Holly gets to know her, Jess isn't fitting the terrible picture Calypso has painted of her.
