I could not put off reading this book any longer.
There are two collections of Le Guin's articles/essays on my Mt. TBR shelf and this is the one that was only recently published (November 2017).
No Time To Spare is a collection of articles from her blog, which you can check out here.
Having read only a few pages so far, it just drives home just what a powerful force of mind we have lost.
One of my favourite post on her blog so far is this one about Amazon - and I am fairly sure that she deliberately abbreviated "Bestseller" and that the term "BS Machine" does not refer to "bestsellers".
