I have read this biography, it´s a good information, but it´s not impartial, the author wrote a lot of his own comments unfortunately!
It was so great and heartbreaking to see my son on stage in the Opera, because he was the son of Anna Karenina!
Now I'm reading Tolstoi's Anna Karenina. Just finished Karamazov Brothers (Dostoievskji). I like Russian literature but classic at all. Above all James Joyce. He was completely crazy but I love him so much.
