Sal stole a map from the school library. She bought a compass, a knife and a first aid kit. She read the SAS Survival Handbook and watched loads of YouTube videos. And now Sal knows how to build a shelter and start a fire. How to estimate distances, snare rabbits and shoot an airgun. And how to protect her sister, Peppa. Because Peppa is ten, which is how old Sal was when Robert started on her ... A disturbing, but uplifting story of survival.
