The Three-Body Problem. Book 7

Van Miao discovers a horrifying truth: an alien civilization is preparing to invade Earth! Even more shocking is the fact that the head of the organization "Earth - Trisolaris" turns out to be none other than his recent acquaintance Ye Wenjie!

She and her supporters firmly believe that surrendering their home planet to the Trisolarans is the only way to help humanity escape the abyss of ignorance. 

But how did the Trisolarans manage to establish contact with Earth? And what was the reason for the formation of the organization?

The answers to all questions lie in the distant past of Ye Wenjie.
