Computer science student Lu Chuan runs into jewelry mogul Shen Qinglan on a stormy night, unaware that their encounter was written into a genetic program twenty years ago. When he discovers that the daisy brand beneath her collarbone is an exact match for his late mother's design, he is even more shocked to learn that his heartbeat is the ultimate key to her safe.
The long-concealed Daisy Project gradually comes to light. Shen Qinglan is a supercarrier created through genetic editing, while Lu Chuan is both her legal heir and the experiment's control subject. And the clones scattered throughout the city are using faces identical to theirs to ignite a corporate war.
As they flee through a world where heartbeats are passwords and genes are shackles, desire takes root amid guns and data streams. Only when Lu Chuan cuts the chip from beneath Shen Qinglan's collarbone with his own hands does he understand his mother's final message: "She is your sheath and your blade, for all eternity."
