Purefriendliness Stories

Sheraia is a 13 year old with an abusive uncle. Her parents died when she was just barely a month old. She has lived with her uncle all her life. He has whipped her, put ciggarrettes out on her skin more times than she can count, and locked her in a closet during her own birthday party and slapped her afterward. One night, her uncle got drunk and purpously shot her best friend, Samantha. She meets Doctor Who. Will they travel back in time to find evidence of her friends shooting and her parents death and prove her uncle guilty, or will the cops think Samantha committed suicide?
