It was supposed to be a relaxing vacation. Even though he can't spend time in the warm waters of Belize, policeman Conrad Bishop is happy to spend time with his girlfriend, Amber, at a private beachfront home in Nantucket. After a tranquil evening walking the beach, Conrad wakes at 3:00 AM, turns on the television, and hears a disturbing news report about a deadly influenza plague-the direct result of a terrorist attack on the United States. Rushing into his bedroom, he finds his girlfriend unconscious and suffering from a high fever. When he tries to take her to the hospital, the town is in a panic. Cars clog the road, and he's forced to return to the beach house. Amber never regains consciousness, and by that evening, she is dead. Grief stricken, Bishop is suddenly thrust into a world that changes by the minute. Terrorists attack every major city in the United States with car bombs and invade American embassies overseas. With a small group of survivors, Conrad struggles to stay alive. His fight will take him to the very steps of the White House and have him waging a valiant crusade to keep a dying nation alive.
