There are some great novel recommendations here, but I wouldn’t say that most of them are lesser-known.
What are your recommendations?
As for me, I’ve exclusively read well-known novels, except if you consider someone like Alfred Bester obscure, for example.
One exception: Misha Burnett’s Endless Summer: Twelve Strange Tales of Mankind’s Future. It’s a collection of exceptionnaly well-crafted stories. It ain’t a novel, though.



Does The Metamorphosis of Prime Intellect by Roger Williams count as lesser-known?
CW: extreme graphic sex and violence, suicidality, neural network AGI a little too close to Big Tech’s wet dreams (eerie for a 1994 novel: self-fulfilling prophecy?)
I love this story so much. I read it years and years ago and found it recently.
