This novel was absolutely wonderful. I was a bit apprehensive upon picking up this book, as Science-Fiction has never really been my genre, but CS Lewis' writing style never disappoints. This man could write about a grain of dirt and it would still be an excellent read. If you enjoy space travel and such, read it. If not, read it anyways. It is far more than just an enrapturing and exciting read, though it is this too, but it also offers much insight into our world, society, and generally how we live in. Though written many years ago, it still provides information and a shrewd understanding of Human nature that still applies today. A definitive must-read.
