One ordinary afternoon, research specialist Dr. Erin Cross enters a small deli for lunch ... and nearly takes a bullet instead. Thanks to the intervention of former Special Ops Marine Sean Flannery, she walks away from the seemingly freak incident. But when she returns to work she finds her lab under security lockdown, and later, that her apartment has been ransacked. She realizes the attack in the deli was anything but random. She can't make sense of the attack given her low profile following a disastrous H1N1 vaccine trial. She is unaware the her former colleague Dr. Jacob Krantz has used her vaccine to develop a deadly bio-weapon he calls the Armageddon Virus, or that his collaborators want her dead before she discovers their evil plans.
Fleeing for safety with her research in hand, Erin seeks the help of the former Marine. But they get closer to unraveling the mystery behind her threats, the more erratic his behavior becomes. His suspicious communication with his daughter and his bipolar swings seem more befitting an enemy than a friend. As the crisis comes to a head, Erin can't be sure who harbors more secrets, the evil organization trying to kill her or the one man who can save her life. (Publisher website)
