This very short century, that begins in 1918 and ends with of Berlin's wall, has its most formidable days pictured in this "saga" about the struggle between totalitarian and democratic states. Still very much mistaken about the former URSS and "socialist paradise" as the tactical alliance imposed at the time of WW2, the facts depicted in these books bring back times that should not be forgotten. The plot is good, although it takes, I believe, some kind of previous knowledge about those days to be followed. All in all, it is perhaps the best and more comprehensive novel, or sequence of novels, about an era that makes the main part of the last century, and will certainly be an important part of future appreciation of our time.
