I've received my copy now. Any new Romanov book is good news and I was especially happy to find out that there would be one focusing on the grand duchesses, but Four Sisters has been even better than I expected. It makes me think that it's still possible to write about the Romanovs in a fresh way and using sources that haven't been completely explored because in addition to covering familiar ground, it is full of new references and quotes that I haven't seen before in Romanov-themed books of popular history or online on royalty forums like this. I don't know if there are rules about whether we are allowed to post specific quotes from a new book, but there were plenty of little details that amused me or even made me stop and reconsider what I knew about someone. The photo section is excellent, with a large number of rare photos that were shared online for the first time only last year, so this must be the first time they appear in an English book.
