Of Other Worlds is a posthumously published collection by C.S. Lewis, offering a dual experience for readers. The first half features Lewis's thoughtful essays on the nature and creation of science fiction and fantasy literature, providing a rare glimpse into his critical mind. The second half presents three of his lesser-known science fiction stories, including one previously unpublished, and the compelling beginning of 'After Ten Years,' an unfinished novel inspired by the aftermath of the Trojan War. This book is ideal for mature young readers and adults interested in literary theory, the craft of writing, and diverse imaginative narratives from a master storyteller.
