The first book of the three-volume set “Sails of the Espada” includes the trilogy novel “The Boy with a Sword” - a work that, back in the seventies, immediately after its publication, received cult status. In the image and likeness of the pioneer detachment “Espada” depicted in the novel, out-of-school children's associations began to be created throughout the country. Based on the book, the television series “Riders at Rosa Station” and “Boy with a Sword” were filmed (unfortunately, it is now impossible to watch them - the recordings have not survived).
