Planet Narnia

The May, 2008, issue of First Things had a review of Planet Narnia: The Seven Heavens in the ­Imagination of C.S. Lewis by Michael Ward. The review covers the book's argument that each of the books in The Chronicles of Narnia has an equivalent planet. As the reviewer Nathaniel Peters puts it:

Each of the seven planets of the ancient celestial hierarchy provides the atmospheric superstructure for each of the seven books in Lewis’ series of children’s books.
