Yves and his squad went in search of the last beech from the “Tablet of Wisdom”. It turns out that the most dangerous path from the Sacred Stone led to her, on which it is easy to lose yourself and difficult to find. The fourth book in the series “Ivashka in the Thirtieth Kingdom” will continue the story of the adventures of Iv and his team. The Great Assa is coming - a confrontation between the light and dark gods of the Slavs, a confrontation between two artificial intelligences - IRa and VikA. And, as always, our heroes will find themselves at the edge of the blade - in the center of events. But will the sword remain a sword or will it be possible to forge it into a plowshare? It all depends on the path that Yves and his squad will choose on the Path of the Magus.
