Young Nathan Andrews was a child who lost his mother to cancer. Now his deepest wish is to become a doctor. When a stranger named Robert gave him the money to buy his mother a pair of shoes for her last Christmas, both Robert and Nathan learned the deepest lessons of love and giving. Now a medical student in his third year, Nathan realizes there are still things to be learned about faith, blessings, and sacrifice. Lessons he will learn from Meghan Sullivan-a young woman born with a hole in her heart that has not kept her from becoming a champion runner. And lessons learned from a young boy named Charlie, who teaches how to live a life of true courage. Together, they will help guide Nathan through the darkest period in his life.
