This book is dedicated to one of the most dramatic periods of our history, which predetermined the fate of not only the USSR, but also modern Russia. The question was being decided whether or not to be accelerated industrialization (the fruits of which we still enjoy). A direct clash included the largest clans in the leadership of the USSR - the conditional "right" (Bukharin, Rykov and Tomsky) conditional "left" (Trotsky, Zinoviev, Kamenev, Sokolnikov and Krupskaya) and Stalin's group, which played its own game.
