on Earth, leaving only the kids behind. With her parents gone, Lisa is responsible for her little brother, Todd. She has to make sure they stay alive. Many kids are sick or starving, and fierce gangs are stealing and destroying everything they find. Lots of people have given up, but on Grand Avenue, some kids are surviving. Because of Lisa.

Lisa figured out how to give the kids on Grand Avenue food, homes, and protection against the gangs. But Tom Logan and his army are determined to take that away and rule the streets themselves. How long can Lisa's group keep fighting them off? They need to find a place to live safely. A strong place. A secret place.

In a world like this, someone has to take charge. But does Lisa have the strength to take charge of a whole city?
