High Quality Content by WIKIPEDIA articles! Of Other Worlds is a 1966 anthology of literary criticism by C. S. Lewis and published posthumously by the executors of his estate. It was edited by Lewis` secretary and eventual literary executor Walter Hooper. The first part of the anthology consists of several essays that cover Lewis` ideas about the creation of science fiction or fantasy literature. Unreal Estates is the transcript of a recorded conversation between Lewis and the authors Brian Aldiss and Kingsley Amis that took place in Lewis` rooms in Magdalene College "a short while before illness forced him to retire." The second part of the book is made up of three of Lewis` previously unpublished science fiction stories and the beginnings of a novel set during the aftermath of the Trojan War.
