I am thinking maybe I should get this. Speaking Swedish (though not 100% fluently), I can read Danish as well to a degree. Looking at the website, the book says it is her 1917 - 1919 diaries, written while under housearrest, day to day life under arrest, despair over the tsar's family, etc. It says it is well illustrated with previously unpublished photos.
If I get it (it is quite expensive at NZ$88 + postage on top of that...), and have time, I could post some sketchy translations from it...
