About This Book

Book Summary

From the author of Once More We Saw Stars comes a gripping novel about four intertwined lives that collide in the wake of a mysterious tragedy. Set in a near-future world where the boundaries between human and AI blur, the story challenges our understanding of consciousness and humanity.

Anna is shattered by the violent death of her son, Alex, and tormented by the question of whether it was an accident or a suicide. Samantha is Alex's best friend, and the only eyewitness to his death. She keeps returning to the cliff where she watched him either jump or fall, trying to sift through the shards. Aviva is an "upload," a digital entity composed of the sense memories of a human tether. But she's "emancipated," having left her human behind. Set free from her source and harboring a troubling secret, she finds temporary solace in the body of Cathy, a self-destructive ex-addict turned AI professor and upload-rights activist.

With UnWorld, Jayson Greene envisions a grim but eerily familiar near-future where all lines have blurred—between visceral and digital, human and machine, real and unreal. As Anna, Cathy, Sam, and Aviva's stories hurtle toward each other, the stakes of UnWorld reveal themselves with electrifying intensity: What happens to the soul when it is splintered by grief? Where does love reside except in memory? What does it mean to be conscious, to be human, to be alive?

Media Reviews

The Boston Globe
A lightly speculative story where intelligence may be artificial, but emotions are painfully real... . The best of UnWorld marks a writer to watch.

Kirkus Reviews
A mesmerizing novel in which boundaries between human and digital are as blurred as those between reality and imagination.

Publishers Weekly (starred review)
Haunting and deeply introspective...Greene crafts a stunning narrative that is as emotionally resonant as it is thought-provoking, weaving together mystery and philosophical speculation with graceful, evocative prose. The result is a mesmerizing meditation on loss, technology, and the enduring nature of human connection.

Author Blurb Hanif Abdurraqib, author of There's Always This Year
UnWorld is a richly layered, deeply intimate novel that holds a mirror to the depths of our own loneliness and offers a meditation on how to continually love ourselves through a cascade of grief that changes but doesn't end.

Author Blurb Suleika Jaouad, author of Between Two Kingdoms
Gripping, tender, haunting, and so gorgeously written, UnWorld is a staggeringly beautiful debut novel. With nuance and subtlety, with grace and deep feeling, Jayson Greene writes about the most ancient of human stories of love and grief, alongside the pressing, hypermodern concerns of the digital age, like artificial intelligence. On an idea level, on an emotional level, and on a sentence level, I was entranced.
