Not that anyone else cares about her beyond getting the deadpool points....but as someone who had heard of her before she got ill (see above), I can recommend her books. IMO there is a strong Doris Lessing influence to her work, although Diski might not agree with this assessment.   Not a stranger to taxing mental states herself, Diski writes very eloquently about madness and, as well as some of her more recent tweets, Rainforest (1990, available here for just 1p + P&P) is an excellent example of a descent into insanity...   Not her daughter, although Diski was taken in - basically off the streets- by Lessing in the early 1960s.
