"After a devastating epidemic that changes the very nature of humans, two sisters, an epidemiologist, and a neurobiologist hold the key to humanity's survival."-Library Journal

BEGINNING OF THE END

They call it Pandoravirus. It attacks the brain. Anyone infected may explode in uncontrollable rage. Blind to pain, empty of emotion, the infected hunt and are hunted. They attack without warning and without mercy. Their numbers spread unchecked. There is no known cure.

Emma Miller studies diseases for a living-until she catches the virus. Now she's the one being studied by the U.S. government and by her twin sister, neuroscientist Isabel Miller. Rival factions debate whether to treat the infected like rabid animals to be put down, or victims deserving compassion. As Isabel fights for her sister's life, the infected are massing for an epic battle of survival. And it looks like Emma is leading the way . . .
