The PEN New England Award–winning author returns to Egypt, Maine, where revolution is brewing in a rural compound as the twenty-first century approaches.

It's September 1999, and Gordon St. Onge, known as "The Prophet", presides over his controversial Settlement in rural Maine. It is rumored to be a cult, where his many wives and children live off the land and off the grid. The newest member, fifteen year old Brianna Vandermast, is fired up and ready for change. Forming her own militia, Bree spreads her vision by writing "The Recipe", an incendiary revolutionary document that winds up in the hands of wealthy elites—including one who is about to have a fateful encounter with Gordon.

A chance drinking session during an airport layover brings Gordon together with multinational CEO Bruce Hummer. Bruce hands Gordon a mysterious brass key which has the potential to spark the unrest that is stirring in Egypt, Maine. As word of "The Recipe" spreads, myriad factions from across the country arrive at The Settlement wanting to make Gordon their poster boy. Gordon soon finds himself at the center of an uprising, the consequences of which no one can predict.
