This book was a great read. Having studied this area earlier in the year, I wanted to do some extra research and this certainly fulfilled that purpose.
As it says in the title it covers 1917-1929, which means the Revolution, the Civil War and the power struggle. It does go into depth about the economic policies such as the NEP, The Five Year Plans and Collectivization. I think Carr manages to strike a nice balance between the politics and economic issues so you get a nice scope into both areas, it is nicely organised into chapters - so you can dip in and out depending on your needs. It also has a brief but insightful summary at the end about how effective/significant the revolution was. For those who don't know, E.H.Carr is widely regarded in this area so it's written by a reliable author and is well sourced.
The language isn't too complicated, it's easy enough to get through and it's not very intimidating in size making it very student friendly. I found that it covered some extra areas that we had only touched on in lessons such as the USSR's relationship with the rest of the world. It made some interesting points about Stalin and his motives.
I think this is an excellent book, if you're a student it will be a nice revision aid or read-around-the-subject material. If you are just generally curious about Russian history this would also suit you, it's relatively easy to understand and covers all the main areas of interest.
