Speak written by Laurie Halse Anderson.
I bought it last night and couldnt put it down. I just finished it a few minutes ago.
Its about a new freshman named Melinda who got rapred over the summer and couldnt express her feelings so she became well partly mute. She coudlnt talk about anything.
There is a movie about it also called Speak.
I would recommend it to everyone unless its a triggering subject for you.
