A deadly outbreak in Kenya. A conspiracy beyond imagination. And a race to save humanity in its darkest hour. In a remote village in Kenya, several local residents contract a mysterious disease. The next day, two American aid workers fall ill. The WHO and CDC send teams, led by Dr. Peyton Shaw - an epidemiologist who has stopped some of the most deadly outbreaks in recent history. Peyton is good at her job, but she is driven by her own dark secret - and haunted by mysteries in her past. What Peyton finds in Kenya is an outbreak very different from any she has ever seen. As the pandemic sweeps the globe, Peyton is drawn deeper into a conspiracy of unimaginable scope, a plot that appears to be linked to her past. The answers, and the key to stopping the pandemic, are revelations that carry a price - for all of us.
