Ryan Sterling is a college senior driving home for winter break. The drive is ordinarily uneventful, but not today. He watches in horror as an unknown aircraft causes an explosion so massive that the above ground world is destroyed. Ryan escapes, but he wakes up alone, severely burned, and lying on the basement floor of his parents' home. Left with only delirious dreams and memories of his family and girlfriend, Sara, Ryan is forced to confront the despair of being the only apparent survivor, his lack of faith in God, and the fear that whatever - or whomever - caused the explosion will soon return to finish the job. Over the year to come, Ryan must rediscover hope and conquer his fear so that he can truly survive and thrive in the new reality of a devastated planet. Now that Ryan has lost the world, can he gain his own soul?
