A Friend in Need! — Julia Jarman

When popular Erika is being bullied, she doesn't know who to tell, in the second entry in this series about friendship

Erika is good at sports -- actually she's good at everything -- and she has lots of friends. But her two best friends Daisy and Phoebe are worried about her. She seems really quiet and is avoiding them. If it wasn't Erika they'd be worried she was being bullied, but surely no one would bully the most popular girl in school?
