The Three-Body Problem begins during China’s Cultural Revolution when Ye Wenjie witnesses a tragedy that alters the course of human history. Decades later, nanotech engineer Wang Miao is pulled into an investigation of mysterious scientist suicides that leads to a virtual world dominated by three suns. This novel blends historical depth with speculative physics to create a powerful opening to the series. The Dark Forest expands the series-wide premise: imagine the cosmos as a dangerous forest where any revealed civilization becomes prey. Humanity’s survival depends on secrecy, strategy, and the psychological tension of facing an incoming extraterrestrial threat. This sequel raises the stakes with original technology, grand strategy, and philosophical weight.
