For as long as Halley Steen has known her husband Nathan, he has carried a handful of stones in his pocket. Each day he uses those stones to remind him to follow the Golden Rule, moving a stone from one pocket to the other with each act of kindness. So it's not unusual that Nathan stops to help a stranger on the side of the highway while on his way to his son's football game one Friday evening. But that one act will change all of their lives forever, when a car hydroplanes off the road, killing Nathan instantly.As Halley and her children Ty and Alice struggle with their grief, Nathan's spiritual legacy lives on. A Facebook page appears, where countless stories about Nathan's selfless acts are shared. But among them is one that stands out, from a woman who says that Nathan saved her life.
