What a treat! I find her one of the most interesting Romanovs of the later years. Nice that it is written by a Russian author, so the focus is not completely on the British aspects as is so often the case.
It seems that the book has 400 pictures, which makes me wonder if there is a lot of space for the actual biography. It seems that the book has been published by Arturo Beeche / eurohistory.
It is also for sale at van Hoogstraten bookshop:
Korneva, Galina/Cheboksarova, Tatiana - Grand Duchess Marie Pavl, van Hoogstraten Online Shop
I did not find it on eurohistory.com yet.
