Piper Sullivan School’s best student fell from an observation mountain platform and has been in a coma ever since. Piper’s parents and the police believe it was an accident, but her older sister thinks otherwise. To learn the truth, Savannah joins the “Survival School” club—classes Piper attended shortly before the fall. Savannah goes on a hike to the same mountain where her sister fell, to conduct her own investigation. Everyone in the club is under suspicion, and each person keeps secrets about what happened that tragic day. Was the girl’s fall really an accident? Or did someone want the death of the perfect Piper? If so, who—and for what reason?
