New Places, New identities

My life has turned around and upside down since the day I was born. My parents tell me nothing they just say my life is in danger when we have to pick up and leave. I tried my hardest to fight back and not let them make me move again because I am finally making friends. My name changes as soon as we leave one place to another. One month it could be Sam the next it could Emily but I know for sure that my real name is Emma. That's all my parents told me. I have to sisters and their real names are Bri short for Briana and Courtney. I'm 17, Courtney is 15, and Bri is 14
