First came the virus. Then came the Collapse. The only way to contain the epidemic is mandatory migration across the northern border of the United States. Each vaccinated citizen is identified by a tiny microchip - the most intelligent piece of technology ever to be implanted in a human being that tracks and analyzes your every move. Twenty-year-old Haven Allis is in the system: her Citizen ID tracks her location, conversations, Internet activity, bank account - everything. Any suspicious activity is warrant for arrest. But for those who are undocumented, life is much worse. Illegals are taken to the prisons in Sector X and made to disappear. When her best friend Greyson is captured and arrested for his undocumented status, Haven must go off the grid to save him. Life outside the city has its own dangers: carriers of the virus lurk everywhere, and the Private Military Company is rounding up illegals. On her mission to rescue Greyson, Haven will discover a revolution in motion and be forced to question everything she believes.
