Summer, 2017. About four hundred people leave behind cell phones, credit cards, jobs, houses, families-- all on the same day. Kevin Moore is one of them. Former military, disaffected, restless, Kevin leaves disappears-- into a movement that calls itself the Massive Brigade. Are they a protest organization, a political movement, or a terrorist group? The FBI doesn't know-- but isn't taking any chances. Special Agent Rachel Proulx is very familiar with Martin Bishop, the charismatic leader of the Massive Brigade. She knows they need to find these people before they put their plan into action. And what she uncovers will shock the entire nation. -- adapted from jacket
