Words Not Spoken

The last time I spoke? I don't even remember it, it was so long ago. The reason why, however, burns in the back of my mind like an everlasting flame. Every time someone asks me a question, his words run past my mind.
"Say one word and I will kill you."
Every night I dream of the things he constantly did to me. I wake up screaming into the darkness with tears streaming down my face, realizing that nobody cares to wonder why I'm screaming. Neither of my parents even wonder why I had stopped speaking. They just look at me in disgust and continue with their day.
One boy though, one boy has interest in me, and I don't think he's going to give up until he finds out why I don't speak. My biggest fear is that, if he does find out, will it put him in danger?
