"Time in a circle" is a science fiction book by the famous writer Fritz Leiber. In this work, he tells the story of a time traveler who finds himself trapped in complex loops and spatial twists. The hero has to not only survive in this endless pursuit, but also to unravel the mystery of his own nature and place in the universe. Warmed by the author's spiritistic philosophy, the book "Time in a circle" leaves the reader under the impression and adds new subtexts for thinking about time, space and existence.
