This book is an excellent introduction to what happened from the Lenin to Stalin years in the USSR. Anyone who's curious how a country meant to turn into a Socialist Democracy became a Totalitarian Tyranny will want to read this book! This book enlightens the reader on how that country was corrupted by Stalin, and it also attacks some of the myths spread about the Bolsheviks which are still propagated today ( the German gold idea, for instance ). For those who think that Stalinism is the natural outcome of Bolshevism, read this book; It dispels the myth. This book should be complemented later by books by Trotsky and Isaac Deutscher's biographical trilogy about Lenin's second-in-command as well, but all in all, a great book to start with for understanding the Russian Revolution.
