Space Trilogy: Out of the Silent Planet, Perelandra, That Hideous Strength (Boxed Set)

The Space Trilogy or Cosmic Trilogy is a series of science fiction novels by C. S. Lewis, famous for his later series The Chronicles of Narnia. A philologist named Elwin Ransom is the hero of the first two novels and an important character in the third. The books in the trilogy are: (1) Out of the Silent Planet (1938), set mostly on Mars (Malacandra). In this book, Elwin Ransom voyages to Mars and discovers that Earth is exiled from the rest of the solar system. Far back in Earth's past, it fell to an angelic being known as the Bent Oyarsa, and now, to prevent contamination of the rest of the Solar System ('The Field of Arbol'), it is known as 'the silent planet' (Thulcandra). (2) Perelandra (1943), set mostly on Venus. Also known as Voyage to Venus. Here Dr Ransom journeys to an unspoiled Venus in which the first humanoids have just emerged. (3) That Hideous Strength (1945), set on Earth. A scientific think tank called the N.I.C.E. (The National Institute of Co-ordinated Experiments) is secretly in touch with demonic entities who plan to ravage and lay waste to planet Earth.
