The novel shows the outstanding role of the communists of the 20th century in the implementation of fair solutions to many problems on the globe; an attempt was made to analyze the inevitable mistakes of the Communists and the objective reasons for their rebirth; reflects on what led the Communists at the end of the 20th century to tragedy and what does not allow them to move from an ideologically stagnant point today. Today it is very difficult to determine which book is needed and which is not. Freedom of publication - there would be money! - spawned mountains of books. Go figure out what you need. And yet you can figure it out. You just need to pay attention to what and how the next book considers. If sex, racketeering or a new wave of dirt on the past through fiction is "we have already passed." And if a book on facts, through logic and reflection, tries to convey the truth to the reader, this is "another difference."
