Twenty-five high school seniors emerge from their basement geometry class to an eerie silence in a deserted school. Outside, empty buildings, stores, restaurants, and abandoned cars line Manhattan's once crowded streets. There is no sign of people. Phone calls to distant cities and messages sent on the Internet bring no response. TV channels show empty newsrooms. Human life has disappeared from the entire planet, sparing only twenty-five teens. Stunned disbelief is followed by alarm, curiosity, sorrow...and the horrifying realization that, for better or worse, they have inherited the Earth.
