Sourdough by Robin Sloan

Lois is lost, consumed by her job, her gastrointestinal distress, and not much else. A chance take-out ad begins a strange journey that involves spicy soup, robot arms, secret underground farmers' markets, San Francisco culinary legends (that are definitely NOT Alice Waters), ancient legends, folk music, and a whole lot of sourdough bread. A perfect (quirky) millennial fable. - Jocelyn
