The Young World

New York City is now run by tribes of teenagers, survivors of a
mysterious Sickness that wiped out all adults and little kids. But
they’re only survivors to a point—as soon as they get too old, the
Sickness kills them, too. The teens who remain are left in possession of the bones of a modern world that doesn’t work. With
resources scarce, conflict is inevitable, and the teens make sure
they are armed to the hilt.
The Young World follows Jefferson, the reluctant leader of the
Washington Square tribe, and Donna, his secret crush, as they rally teens around them in an effort to find the cure to the Sickness, and change the world forever
