Observations and Recommendations

So I have noticed that for the last ten books that I've read I have rated seven of them 3.5 stars. I think I am stuck in 3.5 land. Nothing that I have read recently has really stuck out to me or left me amazed. Everything has just been good but not great.

 

Now on to the recommendations...

 

I have been meaning to ask this for a while now and I was reminded of it when I was reading The Last Lion and came across parts about Stalin, can anyone recommend me a good book on Russian/Soviet Union history? I have always wanted to read more about Russia but didn't know where to begin. If you've read a good book or have received a recommendation from someone please let me know.
