The future is no longer a matter of chance. It can be calculated. What begins as a scientific breakthrough calls into question everything we think we know about time. Past, present, and future are not separate-they interact with one another. Five people stumble upon clues to a discovery that was not meant for them. Deep underground, hidden in ancient sites like Göbekli Tepe, the enigmatic relics of the Urfa Man, and the traditions of the Epic of Gilgamesh, they find evidence of knowledge older than any known civilization. And of something that is not human. At the center lies an equation. A model of reality that can do more than it should. But the closer they get to the truth, the clearer it becomes: Some things must not be fully understood. For what happens when the future is no longer open?
