Earth is reeling. American alliances are shaking. And humanity's enemies rally. For six months after the failed alien attack, American Admiral Jack Mattis has been ordered to patrol the periphery, to stop more alien incursions - even though he knows the attackers weren't alien, but grotesque mutated super-humans from the future. A truth world governments publicly deny. And now an American scientist witnesses an experimental super-weapon gone awry at a top-secret genetic lab in deep space, while a rebel veterans group storms a Chinese embassy on an American world. Tensions flare, and the American-Chinese peace begins to fray. Admiral Mattis races to put out the fires, while trying to piece together the mystery of the future human invasion, knowing that failure means not only certain death for him, but for the entire human race. The clock is ticking
