Will their wilderness skills be enough to survive the dangerous Rocky Mountains? First a Canadian Rockies avalanche kills their parents. Then Children’s Services threatens to separate them. That’s when the three Gunnarsson kids decide to run away into the mountains and fend for themselves until the oldest turns eighteen and becomes their legal guardian. Not many would dare. But Jon, Korka, and Aron’s parents ran a survival school. Turns out their plan is full of holes. When food and equipment go missing and illness and injury strike, things get scary. They’re even less prepared for encounters with dangerous animals and a sketchy woods dweller. On top of that, grief, cold, hunger, and sibling infighting threaten to tear them apart, while the search parties are closing in on them. Do Jon, Korka, and Aron really have what it takes to survive?
