After the plane carrying his family home from a wilderness vacation crashes on a remote mountain pass, fourteen year-old John Parker awakens to a scene of unspeakable tragedy. Gravely injured and skirting the lines of consciousness, John Parker must cope with his devastating loss as he quickly undertakes an epic battle for survival. And when his growing obsession with a family secret threatens to drive him to despair, John Parker finds strength in the knowledge that there is another survivor of the crash who desperately needs his help.
