I've heard of Natasha Pulley because one of her other books, The Half Life of Valery K, sounded like something I would really enjoy. But when I looked at reviews and saw many people complaining about historical and cultural inaccuracies and a lack of research into life in the Soviet Union, I ended up not even wanting to try it. It's a pity, because her book descriptions always sound great. But I guess not everybody cares about such inaccuracies.
