An innocent family, carjacked on a desolate highway, is abducted to a bizarre new world. A world being born in the Californian desert. They discover Earth has been invaded by an alien microorganism. The deadly entity attacks like a virus, but survivors of the disease genetically bond with it, developing amazing powers, near-immortality, unnatural desires - and a need to spread the contagion and create a secret colony of the transformed. Now the meaning of "survival" changes. For the babies born in the colony are clearly, undeniably, not human...

In a violent near-future, Asa Elias Doyle and her companions encounter an alien life form so heinous and destructive, they exile themselves in the desert so as not to contaminate other humans. To resist the compulsion to infect others is mental agony, but to succumb is to relinquish humanity and free will. Desperate, they kidnap a doctor and his two daughters as they cross the wasteland--and endanger the world.

In an alternate America marked by volatile class warfare, Blake Maslin is traveling with his teenage twin daughters when their car is ambushed. Their attackers appear sickly yet possess inhuman strength, and they transport Blake's family to an isolated compound. There, the three captives discover that the compound's residents have a highly contagious alien disease that has mutated their DNA to make them powerful, dangerous, and compelled to infect others. If Blake and his daughters do not escape, they will be infected with a virus that will either kill them outright or transform them into outcasts whose very existence is a threat to the world around them. In the following hours, Blake and his daughters each must make a vital choice: risk everything to escape and warn the rest of the world, or accept their new reality -- as well as the uncertain fate of the human race.
