Early in the twenty-second century, many scientists realized that unrelenting global warming would render the Earth uninhabitable within 100 years. Having no viable planet for human migration in the Solar System, the far-sighted Chinese Space Agency plans to send a human expedition to the Earthlike exoplanet Teegarden-B, 12.5 light-years from Earth, to explore it as a potential for humanity to survive. The problem is that no human could survive that long of a space voyage with their present technology, thus they decide to clone a human brain into a robot specially designed for space travel and exoplanet exploration. To assure success, they recruit Dr. Victor Wollstone and his wife, Sara Pang, the only people to have successfully written a human brain into a robot body previously, to help them.

The mission is fraught with risk as the development team strives to launch it in time to get the data they need to save humanity while they battle anti-brain-cloning activists and anti-Chinese moles and saboteurs, and deal with the growing global panic due to the accelerating collapse of Earth’s ecology. When the expedition does finally make it to the destination planet, the human brain-controlled robot is astounded at what he finds. Can the human race get there and survive?
