His very early works — Dymer chap as by Clive Hamilton, a highly metaphysical Utopian fantasy couched as a book-length narrative poem — came before his conversion to Christianity. Most of his later writing, whether directly or indirectly, was Christian apologetics; this was as true of his autobiography Surprised by Joy as of the fantasy The Screwtape Letters ; exp vt The Screwtape Letters and Screwtape Proposes a Toast , in which an older devil writes letters of advice to a younger, devising various means of winning human souls. All three were Christian moralists with a strong interest in allegory or fantasy, and with others, including Owen Barfield , an Anthroposophist they formed a casual society, the Inkling s, during whose meetings they read to each other from works in progress. Lewis's most popular fiction is for children, and is allegorical Fantasy , although it uses many sf devices, including Time Travel , other Dimensions and Parallel Worlds. The kingdom of Narnia , to which various human children travel, is ruled by a lion, Aslan, who is "crucified" by a wicked witch. There are many excitingly described perils, most with a direct Christian allegorical application.

A philologist named Elwin Ransom is the hero of the first two novels and an important character in the third. In , the publishing house Avon now an imprint of HarperCollins published a version of That Hideous Strength specially abridged by C. Lewis entitled The Tortured Planet. An unfinished manuscript published posthumously in , named The Dark Tower by Walter Hooper , its editor,  features Elwin Ransom in a less central role as involved with an experiment that allows its participants to view on a special screen their own location in a parallel universe. Its authenticity was impeached by Lewis scholar Kathryn Lindskoog in her scholarly criticism of Walter Hooper, but in Alastair Fowler established its authenticity when he wrote in the Yale Review that he saw Lewis writing the manuscript that would be subsequently published as The Dark Tower , heard him reading it, and discussed it with him. Lewis stated in a letter to Roger Lancelyn Green : .
What we do when we imagine is to suppose a reshuffling of universals taken from the actual world. When we imagine Britomart we take our idea of "a girl", which is part of our general knowledge, and our idea of "medieval knight", which is another part of our general knowledge, and put them together. To get into imagination itself what we mean by either of the two terms is impossible. They are not imaginations: they are summarised knowledge of the real.
Lewis was by no means the first to write a novel of interplanetary adventure. Jules Verne and H. Wells had envisioned voyages to the moon 60 and 30 years before, and Edgar Rice Burroughs had written countless tales of Mars beginning in with a Princess of Mars. Lewis set out to change the pattern set up by the early masters. The protagonists in Out of the Silent Planet are Weston, Devine and the philologist Ransom — the latter character, it seems, modeled upon Lewis himself.
