As an agent of the Department of Advance Analysis, she's one of a handful of people who knows about the spread of a new virus—one she believes will wipe out mankind. WIth her bosses in denial, she flies to New York to get her ex-fiance Chip to safety.
But he's already been scooped up and quarantined—and so has his adopted daughter. Pursued by her own agency, Ellie will stop at nothing to break Chip out before the virus claims them all.
Outcome is a prequel novella to the Breakers series. It's best to read it before book three.
