Finished
Ursula K. Le Guin's non-fiction collection
A Wave in the Mind: Talks and Essays on the Writer, the Reader, and the Imagination which was a library book. This was a little lighter and, despite being grouped into reasonably distinct categories, felt a little more disjointed than some of her other stuff that I've read. Possibly this was due to most of the pieces being assorted short presentations and "leftover" works from throughout the decades, rather than more formal pieces that were intended for print publication from the beginning.
There's a range of topics which is restricted in its breadth but not its depth, with reminisces about her childhood as the daughter of famous anthropologists and meeting people who are apparently famous in anthropology and the love of literacy instilled by the people around her, and the bulk of it going on to her own experiences and insights as a writer and on the writing business, plus some thought-pieces on unquestioned cultural assumptions* and challenging them, and even a few poems.
Probably the most interesting were the various pieces (there were several of them) about the use of rhythm in both poetry and prose and how it affects the perception of the language used in particular novels, including works by Austen, Tolstoy, Twain, Tolkien, and others. We also get her opinion of the LOTR films, which she liked even as she lamented that the action blockbuster style didn't really lend itself to the true strengths of the story and its narrative, as a postscript to her dedicated essay on Tolkien's use of rhythm.
Mild recommend if you're interested in what writers think about writing, or Le Guin's outlook on specific things in a more general sense. This doesn't have all that much which is specific about the sfnal genre or her own work which might be a draw to particular fans of those worlds and which are probably covered better by one of her other essay collections, but there's some interesting tidbits scattered throughout, which make it worth a look if you want to see them.
* I appreciate that the author took the time to write out a correction and apology for something she herself got wrong about one of those, and
put it up on her website right on the bibliography page. Hopefully the magic of e-books means that particular mistake can now be corrected as she would like (although it probably hasn't been, given how lax about these things publishers can be).
