In a book that is part investigation and part personal odyssey, journalist Katrina Onstad searches for the lost weekend, and how we can get it back. She argues that, once-sacred, our 48 hours of leisure time has been lost to overbooked schedules, pinging devices and encroaching work demands. Suffering herself from "Sunday-night letdown", Onstad digs into the history, positive psychology and the cultural anthropology of the great missing weekend. She pushes back against the all-work-no-fun ethos and follows the trials of people, companies and countries who are vigilantly working to protect their weekend.
