After a spate of apparent suicides among elite scientists, nanotech engineer Wang Miao is asked to infiltrate a secretive cabal. During his investigation, Wang is inducted into a mysterious online game that is the key to humanity’s place in the cosmos and the key to the extinction-level threat it now faces.

1967: Ye Wenjie witnesses Red Guards beat her father to death during China’s Cultural Revolution. This singular event will shape not only the rest of her life but also the future of mankind.

Four decades later, Beijing police ask nanotech engineer Wang Miao to infiltrate a secretive cabal of scientists after a spate of inexplicable suicides. Wang’s investigation will lead him to a mysterious online game and immerse him in a virtual world ruled by the intractable and unpredictable interaction of its three suns.

This is the Three-Body Problem and it is the key to everything: the key to the scientists’ deaths, the key to a conspiracy that spans light-years and the key to the extinction-level threat humanity now faces.
