 Until the 1980s very few books in these genres were written, and even fewer were published, although earlier books, such as by Gogol, were not banned.Of the rare exceptions, Bulgakov in "Master and Margarita" (not published in author's lifetime) and Strugatskies in "Monday Begins on Saturday" introduced magic and mystical creatures into contemporary Soviet reality to satirize it.Another exception was early Soviet writer Alexander Grin, who wrote romantic tales, both realistic and fantastic.
