Our annual shortlist book club is back! We read two novels that were nominated for Best Novel in the Nebula Awards! SB Divya’s “Machinehood” is a near-future story of gig workers, weak AI servants, and rebellious space stations. Jason Sanford’s “Plague Birds” is a post-apocalyptic story about strong AIs and gene-altered people that’s so far in the future that it feels almost like fantasy. Plus: We recommend other books we’ve enjoyed recently!
