"Whoever you are, dear reader," writes Elin Pelin, "from this book you will learn how Yan Bibiyan teamed up with the little devil Fut, how he replaced his head with a clay one, how he then entered the magical realm of the Great Wizard Mirilailai, and how after a series of wonderful and brave adventures he was saved. His sufferings and his struggle to free himself from evil ennobled his soul, hardened his will, made him brave and enterprising. Thus, he ascended to the moon and was able to achieve the dream that has driven uncompromising scientists with wild imagination for centuries."
