Nothing really new here when it comes to information about the despot. The name almost copies Stalin:Court of the Red Tsar by Simon Sebag Montefiore which is a much better book.
It is organized in a slpadash manor. Like getting a bunch of interns to write diffent sections with no effort to create cohesion.
Little bits of information about certain participants is strewn between chapters. Sometimes these are rexplained in a later chapter which I find strange and annoying. Some of the pictures are severely mislabeled like the one where the quote is "The dacha's servants share a joke behind Lazar Kaganovich....". The one servant is immediately recognizable as Vasily Stalin which is not a servant and the female is his daughter Svetlana. Talk about lazy slap together from known sources work.
Avoid this book there are so many well written/researched books out there that are better and more interesting. If I could give it less than one star I would.
Try these booksfor some real insight:
Stalin and His Hangmen: The Tyrant and Those Who Killed for Him
Stalin: The Court of the Red Tsar
