While I enjoyed the premise of the story and the book overall, I found the first person narrative rather tiresome at times. The writing felt forced at points, in large part due to the first person perspective. I also found the constant mentioning of the "end" for the Romanovs tiresome since we clearly all realize what will happen to the family. Such a thing did not require constant repeating.
I did enjoy the twist at the end and the historical detail included. The notes that were included, which were all real, were informative and interesting. However, again I felt sometimes the author forced them into the story rather than it flowing freely.
Overall, an interesting read about the Romanovs' last days.
