“Preventing Turmoil” is Sergey Barannikov’s novel, the second book in the “Mikhail Gushchin” cycle, battle fantasy and alternate history genres. Mikhail’s successes force his enemies to act openly. While Gushchin fights for his life, conspirators become active in the Principality of Rostov, and on the horizon looms an old enemy with whom he will have to fight again. The stakes are too high: if they lose, the Time of Turmoil will come—and the mission to save the family line will fail.
