In a future North America, where the rulers of Panem maintain control through an annual televised survival competition pitting young people from each of the twelve districts against one another, sixteen-year-old Katniss's skills are put to the test when she voluntarily takes her younger sister's place.

When eleven-year-old Gregor and his two-year-old sister are pulled into a strange underground world, they trigger an epic battle involving men, bats, rats, cockroaches, and spiders while on a quest foretold by ancient prophecy.

Eleven-year-old Gregor and his younger sister, Boots, return to the Underworld beneath New York City to find the cure for a terrible plague that threatens the life of their mother, as well as the lives of the people, bats, and rats who populate the underworld.

In the post-apocalyptic nation of Panem, Katniss Everdeen volunteers to take her sister's place in the televised event in which one boy and one girl from each of the twelve districts are chosen to fight to the death until one victor remains.
