The Only Thing That Keeps Me Going

Hi, my name is Charlie (I'm a girl). Though there is no need to hold on to my name, I'm now only known as Number 4. Me and five other boys were taken to this prison. We don't know where we are, just our way around this place.  I'm known as Number 4 because I was the fourth person they stole. I live in Cell 4, I wear an orange jump-suit which has a number 4 printed on the back. The five other boys are my best friends; Louis, Liam, Harry, Niall and Zayn. 

Zayn was the first one to be taken. He is now only known as Number 1. He lives in Cell 1 and wears an orange jump-suit with the number 1 printed on the back. Louis was the second, and is now only known as Number 2. Harry, the third, me, the fourth, Liam the fifth and Niall the sixth. 

These people are trying to squeeze information out of us, but we have nothing to give and we are now prisoners. When can we leave?
