I listened to a classic of science fiction, The Lathe of Heaven (1971), written by Ursula K. Le Guin and narrated by George Guidall, easily one of my favorite voice actors.
George Orr transforms reality through the power of his dreams. He's terrified each time he falls asleep because he can't control what he dreams.
No one else realizes it's happening. Each time George dreams up a new reality, everyone else enters the new continuum unwittingly. His only ally is his psychiatrist, who is secretly developing a dream machine that will replicate George's powers in other people.
This is what science fiction was made for, to help us consider alternate realities, the nature of dreams, and parallel universes. I give Le Guin full marks for investigating these concepts.
But I didn't like the book. I find Le Guin to be humorless and largely unemotional. The characters felt flat and the prose was dry. There was nothing wrong with it, but the stylistic choice to be deadly serious did not suit me.
I have similar criticisms about many, many, many science fiction books, especially those written in the twentieth century. The science fiction writers I love best--Connie Willis, Martha Wells, Becky Chambers, Tom Holt, Tamsyn Muir--can manage thought-provoking speculation without treating character development like an embarrassing hookup they'd really rather forget.
I've been similarly disappointed by Le Guin's fantasy--The Wizard of Earthsea bored me as a teenager--though I did enjoy The Left Hand of Darkness, a pioneering novel about gender. And the short story "The Ones Who Walk Away from Omelas" is terrific. I recommend that as an entry point for anyone wanting to try Le Guin.
For those wanting to learn more about alternate realities and the interconnectedness of everything, you could take psychedelic drugs like mushrooms or LSD, only those are illegal in most places to please don't construe this as legal advice.
A generally less criminal approach would be reading classic authors like Philip K. Dick (only I haven't read him yet, given my prejudice against 20th century speculative fiction writers), or you could read "The Life of Chuck," a Stephen King short story I read last year that I still haven't recovered from, it was that good.
When Covid first hit, I started doing book talks on social media as a way to keep in touch with people. I never got out of the habit. I don't discuss books by my clients, and if I don't like a book, I won't discuss it at all. While I will sometimes focus on craft or offer gentle critical perspectives, as a matter of professional courtesy, I don't trash writers. Unless they're dead. Then the gloves come off.
