In April of 1914, fifteen-year-old C. S. Lewis walked into a sick neighbor's bedroom for a visit. This neighbor, eighteen-year-old Arthur Greeves, was reading a book titled Myths of the Norsemen. Their meeting was a spark that would fan into a flame a friendship that lasted almost fifty years. Drawing on original research of the 296 letters written by Lewis to Greeves that span the life of their friendship, readers will explore the deep, emotional, and raw relationship of two dissimilar people where each unveiled himself to the other in ways they did with no one else. Embedded in this relationship is the trajectory of Lewis's faith journey, starting out as an arrogant skeptic and transforming into the greatest apologist of the last one hundred years. Readers will be drawn into this beautiful friendship and in turn become better friends to those around them.
