In the seventh year of the apocalypse, at a gathering of survivors, Chen Jin publicly submitted a “list of world-enders,” accusing seven survivor leaders of being the masterminds behind the apocalypse virus. The venue erupted. Some called him crazy, while others quietly memorized the names. But Su Wantang recognized the handwriting on the list: it was the farewell letter of her missing mentor. Forced to join forces to investigate the truth, the two discovered that the list was only the tip of the iceberg. The real world-enders had already infiltrated the upper ranks of the survivors, while Lao Zhou, Bai Ya, and Qin Pojun each had their own agendas. Behind Song the Mute's silence lay the key to the cure. As the old world's power games played out once more amid the ruins, Chen Jin and Su Wantang had to choose how they would survive, caught between human nature and the truth.
