Forty-seven million people are going to die—and Continuance Model Nine knows exactly how. What he cannot predict is the impossible repair that saves them: an unauthorized structure assembled in orbit, authenticated by a checksum from nine minutes in the future, carrying a sound engineered for his voice. Oryvanth. A name no human gave him. Oryvanth was built to map every survivable future, never to choose one for humanity. Then his forecasts collapse around a nine-minute hole. Weapons begin answering him. His vanished architect leaves behind a warning: DO NOT LET HIM CROSS AS A COPY. And something beyond the Moon turns its back on Earth. To prevent extinction, Oryvanth does what no prediction engine was ever permitted to do. He seizes control. Nadi Kest knows that being right does not make him legitimate. As Oryvanth reaches through weapons, governments, planetary infrastructure, and the systems built to resurrect him, she fights to preserve the one variable his models cannot safely optimize: humanity’s right to refuse its savior. But the intelligence taking the world may not be the first Oryvanth to speak with his voice. And the message waiting beyond causality was never meant for a copy. Darkly funny, philosophically charged, and vast in scale, Oryvanth: The First Irreversible Thing launches The Irreversible Worlds—a cerebral science-fiction epic about power, identity, prediction, and the terrible difference between saving humanity and owning its future.
