I am also reading this book. I agree simply written and banal.
If you do not have good knowledge of the extended royal family, or, a good familly tree nearby, you will struggle with family that is mentioned. Lots of going to church. Lots of regimental reviews and riding full gallop towards TheTsar.
But
I did find one interesting thing, that I didnot know, and that is Gabriel was imprisoned in Gorohovaya Street, along with
GD Nic Mikail/GD Dmitri Constan/GD Paul Alexander/Ioann, Constantine and Igor Constant/Sergie Michael/ GD Elizabeth and GR George Michael
[ please excuse the shortening of their names] He was released and lived. All the other were murdered.
Can anyone tell me anything about this prison please?
