What is the glue that holds C. S. Lewis's writings, and most specifically his famed Chronicles of Naria together? Many conjectures have been made, but none fully accepted by the academic community.

The seven planets of the medieval world were of great interest to Lewis all of his life, and Ward proposes that these seven planets and their characteristics are played out in the seven books of the Narnia series.
