Imagine discovering that an advanced alien civilization is headed toward Earth, and they'll arrive in 400 years. Now imagine something worse: they've already deployed subatomic particles called sophons that can monitor every human conversation and sabotage scientific progress. How do you plan a defense when your enemy can hear every word and see every plan? This is humanity's predicament in the cosmic chess game that unfolds across centuries. The Trisolaran invasion fleet is coming, but the more immediate threat is the technological stagnation and psychological warfare waged by an enemy who watches our every move. In response, Earth creates the Wallfacer Project - granting four individuals extraordinary powers to develop strategies they must conceal even from themselves. It's a game of cosmic poker where the stakes couldn't be higher: the survival of human civilization itself.
