I am not familiar with Jenny Diski but on reading about her I find that I am familiar with her former husband's tour company Rainbow Tours with whom she and he invented the name Diski. I will search out her travel book if nothing else (I believe she has written one of travels somewhere). It is also interesting that she was semi adopted by Doris Lessing.
I know her from the London Review of Books. I've added a link to their obituary in the post.
Was she a personal friend?
I read a bit about her, but nothing by her. So it is always interesting to be inspired to start.
