@cavyherd Sarah Pinsker: A Song for a New Day. Not sure if this would fit what you’re looking for: set firmly on earth and quite minimally science-fictional. But to me it has a very similar hopeful ethos as Chambers: a tiny but inclusive community, with kindness surviving against the exploitative mainstream and building something better.
@cavyherd cool! Also Pinsker’s other novels have something of a similar ethos (We Are Satellites perhaps more so, Haunt Sweet Home is more horror-adjacent although even there with emphasis on empathy etc.), but her debut is a great place to start!
