It is the year 2007.
The world has been wiped out by a deadly plague that killed all the adults. Without them, children perished of hunger and disease. No more people, no more electricity, no more civilization -- just mildewed houses, overgrown yards, and abandoned cars. Yet on a highway strip outside a small town in Florida, the words "We're Still Here" are painted in letters big enough to be seen from an airplane -- although no planes ever cross the empty sky.
Miraculously, seven children have survived among the ruins. They cannot remember their names, their families, or much else from the Before Time. But they have forged a new family, with new names: Mommy, Hunter, Teacher, Action Figure, Teddy Bear, Baby, and Doll.
They must face each day with enough hope to endure and the strength to realize that there may be nothing out there worth living for. Then one day, a new kid shows up on their doorstep and changes everything. He invites them to join him on a dangerous journey to Washington, to find a man called President if he's still alive -- and seek the answers to the mystery at the heart of the Fire-us.
