C. S. Lewis liked this book a lot. He was a good enough writer to appreciate the art in such a book that is overlooked by people that only like an easy style. Here something so important is being said that the artist doesn't stop to polish the details like Michangelo's "Men Tearing Themselves out of Rocks" the roughness of the texture adds to the final quality of the reality presented. However, many people find this novel strange. It is NOT a spaceship type of novel. The voyage to Arcturus is a paranormal voyage.
