C.S. Lewis 
Space Trilogy 

Also know as The Cosmic Trilogy, The Space Trilogy is a sci-fi (or science fantasy) epic from the author of The Chronicles of Narnia and The Screwtape Letters.Like Narnia, it approaches religious themes through a genre lens; because of humanity’s flawed nature, Earth has been exiled from the rest of the solar system to prevent contamination. The books chronicle a trip to Mars, and then Venus, where man is just developing, and finally return to Earth, which is under the threat of a demonic invasion.Random House of Canada is proud to bring you classic works of literature in ebook form, with the highest quality production values.
