About the book: 2015 / "Black Digger" in the vastness of the Middle Ages! Europe under the hooves of the Mongol conquerors, knights taking a vassal oath to the descendants of Genghis Khan - how can the average person of the 21st century survive in such a world with an unfinished higher, half-forgotten school history course and a complete inability to fight with a sword or forge with a hammer? No laptop with terabytes of useful information, no firearms, no local money. And there is no possibility of reaching out to the powers that be. And who needs such a “secret adviser”, a misfit? But there is a sharp mind, the energy of youth and the desire to create your own corner of civilization with your own hands.!
