The collection "The Frontier of Fire" is dedicated to the events of the Great Standing on the Ugra in 1480. The book includes historical-mystical, historical-adventure, just historical stories and stories. The quiet river Ugra is not only a line of defense, where the fate of young Russia was decided. It is also a mystical frontier, a place where the forces of evil exert terrible pressure on the shelves and on the souls of people. Ancient evil comes to life in souls, but it can be dealt with, because there is even greater power for all strength.
