Severance by Ling Ma

Part workplace drama, part dystopia. Candace Chen, a millennial drone self-sequestered in a Manhattan office tower, is devoted to routine. So she barely notices when a plague of biblical proportions sweeps New York. The fever spreads. Families flee. Companies halt operations. The subways squeak to a halt. Soon entirely alone, still unfevered, she photographs the eerie, abandoned city as the anonymous blogger NY Ghost. Nominee for Best Science Fiction 2018. https://www.goodreads.com/book/show/36348525-severance (302 pgs)
