I absolutely adored JC and her books, she seemed like a lovely lady and Riders etc saw me through some tough times in an unhappy childhood. She was the Tolstoy of the Shires!!
However while it is very very sad (especially for her family) I think that a quick death at 88 in your own home while enjoying a career resurgence is massively preferable to the sad and slow decline and health issues I see in family that are a similar age. She seemed to still be out and about and working until recently.
Hope that's not an inappropriate thing to say but what struck me through the sadness.
