Lingfan Gao has read the novel Sashenka, by the historian Simon Sebag Montefiore:-
This is a writer who had also published a great biography of Stalin, so obviously he has a great knowledge about the fall of the Russian autocracy. I've found it to be one of the best books I have ever read. The storyline is very exciting, being full of suspense and surprises while still concentrating on one story strand. There is a lot of conflict in the book ranging from the heated arguments deciding the fate of many, to the subtlest but most delicate and intricate moments that might not seem to be about conflict. I can immerse myself and absorb myself in the story and characters. A great book, I think!
