When fifteen-year-old Marlee Stanley joins her two sisters and the sons of their family friends on a secretive hike in the middle of the night, she is thrilled and nervous. Battling her conscience, she prays that the hike will go flawlessly and that they will return to the safety of their campsite before their parents wake. The start of the hike is beautiful and wonderfully memorable. In a white flash so fast that Marlee can barely comprehend what has happened, an avalanche crashes into their path. Buried in packed snow, Marlee is forced to remember survival tips learned from her dad and her own research. This group of friends, ages eleven through seventeen, is about to endure bigger challenges than many adults have experienced. Digging out of the packed snow is only the first of many challenges. Injuries, cold, hunger, fatigue, aggressive wildlife and tensions in the group make this a much bigger adventure than they ever imagined. As the kids strive to exhibit Christian values throughout the trials, they learn numerous life lessons. But they are nearly out of food, and their energy is waning quickly. How will they ever reach help?
