Retribution

The government has fallen. The war for humanity has only just begun.

Chris has escaped the Director's control. If only the same could be said for his soul. Tormented by what he did to survive, Chris tracks the Chead across California—desperate to atone by stopping the slaughter. But the creatures are no longer mindless monsters—and there's too many of them. Even for him.

Liz is the last person he expects at his side. She hasn't forgiven his betrayal—and she's not done yelling at him yet. But she hasn't walked away. With the fate of humanity hanging in the balance, can Chris and Liz work together one final time?

Because love may be the only thing that stands between our survival…and our extinction.
