Reporter Emily Baxter survived the alien red rain that blanketed and annihilated the human race. But after the downpour, and the lethal contagion it spread, came an even greater horror: the rampant transformation of the dead into something utterly unearthly.

With a terrifying new form of life emerging from the mutated landscape, Emily’s only hope is to flee toward distant Alaska where she can unite with the survivors who have reached out to her from a remote science facility. The journey from New York will be long and painstaking, and Emily has only her faithful dog and whatever she can carry. But, after discovering a small family of refugees along the way, Emily’s determination to escape the unfolding catastrophe and carve out a new future is renewed. Standing in their way are Earth’s new masters, equally determined to survive and thrive, and possessed of monstrous capabilities Emily and her allies can’t begin to imagine…until they’re face to face with the hideous reality.

In the battle about to begin, there will be no room for mistakes or mercy—only the most ruthless instincts to survive.
