The Duality Bridge (Singularity 2), livre audio

What does it mean to be human?
Elijah Brighton is the face of the Human Resistance Movement. He’s the Olympic-level painter who refused an offer of immortality from the ascenders—the human/machine hybrids who run the world—in solidarity with the legacy humans who will never get a chance to live forever.
Too bad it’s all a complicated web of lies.
Worse, Eli’s not even entirely human. Few know about the ascenders’ genetic experiments that left him… different. Fewer know about the unearthly fugue state that creates his transcendent art—as well as a bridge that lets him speak to the dead. But the Resistance is the one place he can hide from the ascender who knows everything the fugue can do. Because if Marcus finds him, he’ll either use Eli for his own nefarious purposes… or destroy him once and for all.
The Duality Bridge is the second novel in a philosophical hopepunk sci-fi series that explores the intersection of mind, body, and soul in a post-Singularity world.
