'The election happened,' remembers Elizabeth Sherwood-Randall, then deputy secretary of the Department of Energy. 'And then there was radio silence.' Across all departments, similar stories were playing out: Trump appointees were few and far between; those that did show up were shockingly uninformed about the functions of their new workplace. Some even threw away the briefing books that had been prepared for them.

Michael Lewis's brilliant narrative takes us into the engine rooms of a government under attack by its own leaders. In Agriculture the funding of vital programmes like food stamps and school lunches is being slashed. Commerce may not have enough staff to conduct the 2020 Census properly. Over at Energy, where international nuclear risk is managed, it's not clear there will be enough inspectors to track and locate black market uranium before terrorists do.
Lewis finds the linchpins of the System - those public servants whose knowledge, dedication and proactivity keep the machinery running. And he asks them what keeps them up at night.
