What happens when every adult on Earth drops dead? Now, a misfit, a brawler, and a tomboy must band together to fight the rise of a new adolescent Hitler.

On Friday, June 10 at exactly 9:27 a.m. EST, every adult on earth dies.

The children have inherited the earth. And their nightmare is just beginning.

Facing starvation and persued by a relentless sniper bent on killing her, Josie Revelle—an undersized misfit with nowhere to run—embarks on a mad 48-hour journey that takes her places darker than she ever imagined. She finds friendship with Shawnika Williams, a street-smart, hard-punching girl on desperate quest to find her missing brother, and Grace Cavanaugh, a naïve West Virginia farm girl looking for redemption . . . and Josie's about to become an unwilling messiah.

At the end of their path awaits charismatic, megalomaniacal teenage psychopath Zane Barzán, who commands an army of adolescent killers and has been busy building his own blood-soaked empire modeled after Hitler's Third Reich.

Misfit. Brawler. Tomboy. Psychopath. Are they the end of humanity—or a new beginning?
