This is a great book to learn why Lenin was right and to understand why Marxism would not be an actual matter and would not be practicized properly as an proletarian theory in the age of imperialism without Lenin. In a sense, he was Marx of new epoch. It was who was also open the way to Stalin, who was the gretaest leninist, among the availables, of the period of real foundation of communist society. Who was the first founder of communist society. Lenin had saved Marx to retain a mere academic issue in hands of "marxist" academicians. Today we can not find true answer to the question of "why Marx was right" of academic marxists, if we do not read him through Lenin. Verso should publish these old classics with a new translation.
