The Dark Forest
About
Earth knows it will be invaded in four centuries. The alien Trisolarans can monitor all human communication — every strategy, every plan, every scientific breakthrough is visible to the enemy. Humanity's only advantage: the aliens cannot read minds. So Earth selects four Wallfacers — individuals given unlimited resources to develop secret defense plans that exist only inside their own heads. The second volume of the Three-Body trilogy escalates from the first book's intellectual ambitions into something genuinely cosmic. Liu's central concept — the Dark Forest theory of cosmic sociology — is one of the most chilling ideas in modern science fiction, and the novel builds toward it with the patience of a proof and the impact of a revelation. The book that answers the question the first one asked: why is the universe so silent?
