Sal planned for almost a year before they ran. She stole an Ordnance Survey map from the school library, collected a Bear Grylls knife, a compass, waterproof clothes and first aid kit using stolen credit cards. She read the SAS Survival Handbook and watched loads of YouTube videos. Now Sal knows all about how to survive in the wild. And she knows how to protect her little sister, Peppa. Because Peppa is ten, which is how old Sal was when Robert started on her. Filled with the silent, dizzying beauty of rural Scotland, this disturbing, uplifting story of survival, the kindness of strangers and the irrepressible power of sisterly love is bound to capture the hearts of readers from the first page.
