This isn't the best written book -lets just get this out of the way first. 
Its very choppy, jumps sometimes forward in plot without warning as if the author didn't know where to go and just decided to start a new chapter at a different point in the story and the characters could have been better developed. 

Also i am confused as to if this is non-fiction or fiction? 
If its non-fiction way was it on the longlist for a Fiction book award and if its fiction why is it called a memoir?

All that being said. 
This was still a good story. 
It was interesting and had good ideas in the sense that the characters were interesting with what we got in the story. Sure i would have loved to get more story, more background, more feelings and deeper understanding of the characters and not just what felt like skimping on top of the characters and what they could be. 

But the story itself was still interesting to me. 
I really liked reading about the sisters, about their relationship that wasn't really a sibling relationship in the typical sense but more of a combination of co-dependent need for each other, mostly because the older one seemed to have done most of the raising of the younger one, since the parents apparently where busy being and doing what ever they did for the most part. But at the same time it was also filled with very typical sibling behavior - the jealousy, the hopes and dreams, the wishes, the love and affection and the hate and dislike for the other that can seemingly switch without real warning and with just a small gesture that nobody else would know how to read but siblings jump on in milliseconds. 

I loved the language aspects and wish we would have gotten more form this and gotten a deeper understanding on it all with the characters. 

This book could have been more and better and hit deeper if it would have gotten more pages, if it would have gotten more development, and character depth... just ... more in general. 


But i do think that it's a good read as it is. 

And i think listening to it via audio is a good choice for this, since the slavic languages are read by someone that to my untrained ear sounded like someone that spoke the language well and gave the audio a bit of something extra, more than if i would have just seen those words that i can't understand on a page that i would just have looked over and moved on.
