A girl tries to survive with her friends in the end of the world. Will she survive?

In this story it bounces from Johns character to Memphis's character throughout. It's about Halo. Memphis is a twelve year old girl in a world of war. Her parents were killed in a fire caused by a permethian attack. She lived in six foster homes for four years. UNSC found her listening to music in a tree at twelve, she's the newest recruit, and UNSC is making her a super soldier to help fight the war. Will she survive the war, or her teammates? Johns parents died in a car crash caused by a covenant attack when John was eight. He spent two years of his life in four foster homes. UNSC found him at ten climbing a dangerously tall tree. He's the fastest learner out of anyone here. Oh, and don't think you're gonna get a glimpse of what he looks like, he never takes off his helmet. *If you play Halo, you know who John is.*
