Half a century after the Doomsday Battle, the deterrence of the Dark Forest has kept the Trisolarans from invading.

It's an unstable balance, but the influx of Trisolaran knowledge has ushered Earth into an unprecedented age of prosperity. As human science advances and the Trisolarans embrace Earth's culture, it seems the two civilizations can coexist peacefully as equals, without the terrifying threat of mutual annihilation. But has peace made humanity complacent?
