Kat tries to save mankind from an ever-growing number of threats. Besides the insane General from the Midwest, there's also the original nanobot infection, the question of where all the infected are and now the fear of nuclear meltdowns at power plants across the abandoned East coast.

Kat's personal life crashes and burns along with half of the nation. She struggles across the country to find her friends and it's no easy feat with Carch hot on her tail. They make a horrifying discovery, a game changer- and not one in their favor. Kat tries so hard, but will it be enough? You'll only find out by getting Shocked!
