No, I haven't. I have read the biography of Sissi by Joan Haslip though. It gave me some knowledge of the subject, it is accurate. I should look up the other book ( Hamann's), although I haven't got around to it yet. Its interesting you should mention this book, by Cartland, because I was just on Amazon ( looking for books about Sissi other than the only one I had read), and I saw there was a book on Sissi by Barbara Cartland, who I have only heard of because I am a Princess Diana fan, and she liked her books as a teenager, and was a relative of Diana's stepmother. But, I was wondering what the book was like, although I figured it wouldn't be much good. Thanks for enlightening me, it sounds like I was right.
