The last subway train heads toward the day before the apocalypse. You must get home before daybreak.
At the "Yesterday" platform, caught in a rift in time, Lin Che is searching for his younger sister when he stumbles upon the secret of two worlds. This is no ruin, but evidence of a crime carefully preserved.
As martial-arts powerhouses and tech conglomerates fight over fragments of time, and the number of last-train departures dwindles because of their plunder, he discovers that his sister's disappearance, the world's division, and even the so-called apocalypse all point to the same conspiracy.
Every journey back and forth is a race against forgetting. Every exploration shakes the foundations of reality.
