In the first book of the three-volume set “Sails of Espada” is included the novel trilogy “The Boy with a Sword”—a work that, back in the seventies, immediately after its release received cult status. In the same way as the pioneer squad “Espada” depicted in the novel, extracurricular children’s groups began to be created across the country. Based on the book, TV series were made: “Riders at the Rosа Station” and “The Boy with a Sword” (unfortunately, now it’s impossible to watch them—the recordings have not been preserved).
