Intrigued? Well read on to discover the synopsis and an excerpt in print and audiobook formats from Jayson Greene’s UnWorld, which is out June 17th 2025.
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?
