Unlock the secret to Narnia that has mystified readers for over half a century . . . Millions of people have been captivated by C. S. Lewis’s classic Chronicles of Narnia—but some questions have never been successfully answered. Why are there seven books? Why are only three of them obvious biblical allegories? Does the series lack coherence, as Lewis’s critics (and even some of his friends) claimed? Many have attempted to discover the organizing key— the “secret code”—of the series, but the structure of Narnia’s symbolism has remained a mystery. Until now. In The Narnia Code, Michael Ward presents an astonishing literary discovery. Drawing on the whole range of Lewis’s writings, Ward reveals the single subject that provides the link between all seven novels. He explains how Lewis structured the series, why he kept the code secret, and what it shows about his understanding of the universe and the Christian faith. Originally published as the groundbreaking scholarly work Planet Narnia, this accessible adaptation holds the key to reading the Chronicles and understanding Lewis in a whole new way.
