Florida, 2026. Will Piper, former FBI agent, is retired and living a life of leisure, his thoughts far from the notorious Doomsday Killer case that vaulted him into minor celebrity status 15 years earlier. But according to what that investigation uncovered at a secret government site in Nevada, the world will change irrevocably on February 9, 2027. When a new Doomsday Killer emerges -- inexplicably targeting only Chinese people -- and Will's son, Phillip, disappears, he is instantly drawn back into the case.
