When nothing is left, what will you treasure most?

In a world completely destroyed by adults, eleven-year-old Nic believes he is the only thing still alive after four years of isolation—the only thing except for the Scavengers.

When he meets Celia, another child in an empty world, they offer one another hope and the promise of an end to the kind of fear and loneliness that only a child abandoned on a dead and forsaken planet could understand.

But Nic's universe, for years centered around Celia, will be tested, and he’ll discover just how far he’s willing to go to protect them both.
