Speak

Anderson, L. H. (1999). Speak. NY: Penguin

It's the first day of high school for Melinda.  Her friends won't speak to her, the other students laugh at her. She is holding in a secret she wishes she could tell her former friend Rachel.  Melinda's lips are swollen and bitten from trying to hold in her secret. Jane doesn't speak much in class or to other people socially. She spends much time in a janitor's supply closet.  Her grades suffer and she eventually begins skipping school in an effort to avoid contact with people.  One day, a boy she calls "IT" sneaks up behind her, calling her fresh meat. He makes her nauseous and she runs away.  Later, Melinda has a flashback of a party. First she is having a good time dancing with a boy, then he is forcing himself upon her. The boy is IT, Andy, and Melinda soon learns that she is not his only victim. This gives her confidence to tell her secret to an adult.
I would recommend this book for readers 13 and up.  Teenagers will relate to the theme of being
alone with no one to turn to.
