An essential guide to one of the most influential writers of the 20th centuryA Brief Guide to C. S. Lewis explores Lewis's life, from his reconversion to Christianity under the influence of his friend J. R. R. Tolkien, which had such a profound influence on his writing to his marriage to American writer Joy Davidman Gresham and his battle with cancer. Perhaps best known as the author of the seven Chronicles of Narnia, published between 1949 and 1954, Lewis also wrote The Pilgrim's Regress, a trilogy of science-fiction novels incorporating Christian themes, and a large number of non-fiction books about his faith, accessible to Christians and non-believers alike. The guide provides synopses of Lewis's fiction, an overview of his other writings, a biography and a look at all the many different versions of his stories that have appeared. In doing so it draws on recent interviews by the author with some of the many talented people who have worked on these adaptations.
