The novel based on the Netflix blockbuster "Three-Body Problem." China, late 1960s: While the Cultural Revolution rages across the country, a small group of astrophysicists, political commissars, and engineers begins a top-secret research project. Their mission: to send signals into space and establish contact with extraterrestrials before any other nation. Fifty years later, this vision becomes reality—in a way so terrifying, transformative, and global that this contact will forever change the fate of humanity.
