Triple Lie

Hi. I'm 12. I have three names, but the one you will need to know is my real name. Ashly Miller. My step dad wants to get to me but I can't let him. I hold the only thing that proves that he is the leader of a gang. What he doesn't know is I'm in his gang that I hold the only thing that unlocks the secrets about his gang. My step-brother is the only thing standing in my way of going back to my mom. He knows something about me. I don't know what.
