Science-fiction film directors love to place their characters in virtual worlds. The physical body only twitches slightly, and the heroes seem to be running through mountains and valleys, saving someone, saving themselves... Well, find me the differences between these heroes and the reader! Without electricity and wires, without ingenious schemes, the book does what something that scientists are still only fantasizing about. So, a book is a device that is able to launch the reader into a virtual world created by the author. And we will talk about how these worlds are created and how to make the reader really become completely ours, and his body twitches slightly. We will talk about the master of new realities, about the writer.
