Action, reaction . . .

In the apocalypse, cause and effect can have fatal consequences.

In a powerless world with society in full-on collapse, the appearance of an aerial drone does nothing to comfort Frank and his crew. The voice behind it knows many things about Frank's people, but he also shares critical details about the enemies surrounding Clownfish Cove. Details that could give them huge advantages . . .

But can Frank trust him?

And that is only one problem of many plaguing the street. The sheriff sends a curveball into the watch area, prompting Frank to embark on a desperate mission to rescue the family of a potential new member of their neighborhood.

That's where Frank learns he kicked off a chain of events on day 1 that is now putting teenagers in grave danger a week later . . .

He fights through another night to save all those he can, but will exhaustion finally be the enemy that brings him down?
