Virginia Moffat’s excellent overview of Ursula Le Guin’s work (PN 2672) had me searching my bookshelves to see if any of the anthologies there have the short stories she mentioned.
I’d add two points. Firstly, Le Guin is very funny when she wants to be: dry, arch and only slightly world(s)-weary.
Secondly, I’d recommend The Lathe of Heaven, a novel from the early 1970s.
A man goes to a psychiatrist, fearing for his sanity. The psychiatrist soon deduces that what his patient thinks is a delusion – that his dreams control the future – is in fact true.
The psychiatrist hopes to get rich and famous by manipulating his patient.
One interesting feature is that, although the dreams can be guided in some directions, there is one unalterable factor – the steady climb in carbon dioxide concentrations and the consequences for the world’s climate.
Le Guin was, typically, decades ahead of her time.
