Candace Chen, a millennial drone self-sequestered in a Manhattan office tower, is devoted to routine. With the recent passing of her Chinese immigrant parents, she’s had her fill of uncertainty. She’s content just to carry on: She goes to work, troubleshoots the teen-targeted Gemstone Bible, watches movies in a Greenpoint basement with her boyfriend. So Candace barely notices when a plague of biblical proportions sweeps New York. Then Shen Fever spreads. Families flee. Companies cease operations. The subways screech to a halt. Her bosses enlist her as part of a dwindling skeleton crew with a big end-date payoff. Soon entirely alone, still unfevered, she photographs the eerie, abandoned city as the anonymous blogger NY Ghost. Enter a group of survivors, led by the power-hungry IT tech Bob. They’re traveling to a place called the Facility, where, Bob promises, they will have everything they need to start society anew. But Candace is carrying a secret she knows Bob will exploit. Should she escape from her rescuers?
