Marina Stepnova is the worthy heir of the great Russian author Dostoevsky or Tolstoy ea In 445 pages of dense and thorough writing, she recounts the life of Lazarus, brilliant scientist and, at the same time (and primarily) a century of history. And if it is a country that went through the twentieth of a chaotic way it is Holy Russia became the USSR with its share of Gulags until démantellement Gorbachev. In summary a mighty work as few are able to write today. A must!
