Shy, mild Mandy has been bullied at school for as long as she can remember. That's why she is delighted when cheeky, daring, full-of-fun Tanya picks her as a friend. Mum isn't happy - she thinks Tanya's a BAD GIRL and a bad influence on her daughter. But Mandy loves spending time with her brilliant new friend, and is sure Tanya can only get her out of trouble, not into it . . . or could she?
