A compelling yet soothing tale about a non-binary monk having a midlife crisis.
Topics: finding purpose in life, wilderness, the nature of consciousness, and more.
No violence, no struggle apart from that of a person against the pressures of exertion and survival outside of human civilization, and yet it is a page-turner.
It gets the "solarpunk" label because the setting is a human society which fits the bill: non-capitalist, low-impact technology. Main transport method: "ox-bikes," apparently the author's neologism to refer to electronically assisted bicycles that pull carts around. Personal computers are computers that last a person's entire life. Half of the available land is set aside for wilderness. Etc.
100% recommend. It would probably be a good introduction to science fiction for someone who's not familiar with the genre as it exists in the 21st century.
