The book has been available in Spain for some time. I leafed through it in an airport a short time ago and clearly the author did their best to make the most tenuous links to Olga appear to be firm proof that this lady was who she said she was... it goes without saying that her appearance was nothing like that of the twenty year old Grandduchess, nor did she resemble the family in any way... the book was in the historical novel section though, not non-fiction or biography.
