The life and times of C. S. Lewis's modern spiritual classicMere Christianity, C. S. Lewis's eloquent defense of the Christian faith, originated as a series of BBC radio talks broadcast during the dark days of World War Two. Here is the story of the extraordinary life and afterlife of this influential and inspiring book. George Marsden describes how Lewis gradually went from being an atheist to a committed Anglican-famously converting to Christianity in 1931 after conversing into the night with his friends J. R. R. Tolkien and Hugh Dyson-and how his plainspoken case for Christianity went on to become one of the most beloved spiritual books of all time.
