The Dark Forest

In The Dark Forest, the second novel in a trilogy by the multiple award-winning author of Remembrance of Earth’s Past, a series set four centuries in the future, humanity is reeling from the revelation of a coming alien invasion. The collaborationist human faction has been defeated, but the presence of subatomic particles called sophons—which allow Trisolaris instant access to all human information—means that Earth's defense plans are exposed to enemies. Only human minds remain secret. To protect against that vulnerability, scientists and statesmen devise an unprecedented plan: they select four men to be Wallfacers, each given enormous resources to design secret strategies hidden through deceit and misdirection from Earth and Trisolaris alike. Three are influential statesmen and scientists; the fourth is an unknown.
