Katie Cassidy: Katie is the main character in the book. She is a very nice person and wants to help everybody. She’s also very fair but she’s going to lie when she has to help a good friend. She’s got dark-brown hair until the shoulders and a small posture. She’s afraid for Ivy Toner and her gang but Zan helps her.
Zan: Katie meets a girl on the dump and she calls her ‘Zan’. Zan is a girl that runs away from home and lives in a cardboard box now. She has the same looks as Katie. Unlike Katie, Zan isn’t afraid for Ivy and her gang and she defends Katie with fighting. But she only fights when she has to.
Ivy Toner: Ivy is the girl that bullies Katie. She’s not a good person but she changes in the book because Zan teaches her a lesson and then she’s going to be a shy person. She always got 2 friends by her (that makes the gang complete), they are Lindy Harkins and Michelle Thomson. Katie just thinks that they’re stupid, because when Ivy is not with them, they don’t dare to bully Katie.
Nazeem: Nazeem is a girl that wants Katie’s (and Zan’s) help. Why she needs that help you can read in the plot. She’s going to be a good friend of Katie. And she talks a lot.
