This book is a fascinating read. Michael Ward attempts to prove that each book of the Narnia series is based on one of the seven medieval planets. Although I think that some of the details Ward points out are stretching a bit too far, in general, I think he makes his point well. Having read this book puts a whole new perspective on what the Narnia books read, and I think for the better. Ward does not take away from the Christian elements of the series, rather he shows how the planetary interpretation enhances the Christian message. I highly recommend this book to anyone who is interested in Lewis and his writing.
