As a writer, a reader, and an ardent admirer of C.S. Lewis, Planet Narnia is one of the most eye-opening books I've ever read. I read this on the heels of finishing up Lewis's own The Discarded Image, not realizing how closely the two were related. Reading The Chronicles of Narnia and The Space Trilogy will now be a much richer, more intellectual exercise for me. I recommend this book without reservation.
