In the dystopian city of Jiangluo, which is ruled by the Efficiency Report, Lin Xia (a working-class woman), Chen Ran (a middle-class male analyst), and Zhao Jing (the daughter of an upper-class conglomerate) gain secret access to the Ledger, a system interface that provides real-time economic data cheat codes. Using market manipulation to alter their fates and cope with familial pressures, the trio jostles for position in a tragic cycle of social climbing and bankruptcy. In a world where Pareto efficiency reigns supreme—where one person’s wealth can only grow by sacrificing others—they must choose: sacrifice their blood ties for the pinnacle of power or be crushed by the system.
