Candace Chen is a routine-obsessed millennial drone who works alone in a Manhattan office building. She has experienced enough uncertainty after her Chinese immigrants parents recently passed away. She's content to just keep doing what she's doing: going to work, fixing the Gemstone Bible for teens, and watching movies in a basement in Greenpoint with her partner.

So when a scourge of biblical proportions sweeps New York, Candace hardly pays it any attention. Shen Fever then spreads. Families run away. Businesses stop operating. The subways come to a grinding halt. Her employers hire her as a member of a shrinking skeleton team with a significant end-date reward. As the fictitious blogger NY Ghost, she soon finds herself completely alone and unfevered as she captures the creepy, deserted metropolis.

But Candace won't be able to survive by herself indefinitely. Here come the survivors, led by the ferocious IT specialist Bob. They are headed to a location known as the Facility, where Bob assures them that they will have everything they need to rebuild society. But Candace has a secret that she is certain Bob would use against her. Does she need to flee from her rescuers?
