The nation is in ruins . . .

Food is scarce. Fuel is gone. Medication is out of reach. Seventeen-year-old Zaley Mattazollo and her friends are fighting for the basics of survival as the last vestiges of civilization crumble. The harbor in Sonoma is the only safe place for them to be, but it’s under siege by Shepherds trying to slaughter the Sombra Cs inside.

They are trapped in an impossible situation. When rumor comes of a nearby military base supplying Zyllevir, they are left with no choice but to attempt to cross miles of lawless wilderness to see if it’s true. And if not, Zaley is going to lose everyone forever.
