Twelve-year-old Atlas Wade has been trying to forget the memory of his mother by climbing mountains ever since she died three years ago. When his father signs them up for an expedition group hoping to be the first to ever summit the unconquerable Mount Everest, Atlas can’t wait for the chance to prove himself to his father, and fix the rift between them caused by his mother’s death. But when the threat of a Nazi spy coupled with an avalanche puts his journey through brutal terrain in danger, can Atlas find the strength to let the past go, and find survivors. Or will he be too late?
