The first 150 pages were slow. The sisters were constantly bickering with each other, one was always jogging and the other taking pictures with her camera.
Then finally the younger sister Nina was able to break through her cold hearted mother's defenses (with the help of some vodka) and get her talking about "The fairy Tale" which turned out to not be a fairy tale but the story of the Soviet Union under Stalin and how she survived the Leningrad invasion by Hitler's army.
Anya's story is very heartbreaking the atrocities she endured is beyond human imagination. I found the ending to be satisfactory maybe just a little to happy.
