From best friend to bully

"'I'm just kidding! You're so sensitive!' Emily had heard her friend, Pam, say this more than a few times. It was what Pam said every time she hurt Emily's feelings. Emily always forgave Pam. After all, they were best friends. But now things were different. Pam was definitely not kidding. She was calling Emily names and making fun of her in front of their entire class. 'It sounds like your best friend is a bully, ' Emily's brother told her. Emily was no longer sure she could forgive Pam. In fact, she wasn't sure she could even be her friend anymore."--Back cover.
