The Hunger Games.
The Hunger Games is set in North America. It is set about 250 years after a nuclear war destroys the United States. Survivors of the war formed a nation called Panem. It is made of 12 districts and a central Capitol. When the nation was young, it was similar to the democratic republic that the United States currently is. As the nation became older, it became more corrupt. It changed into a totalitarian police state. The population of the Capitol stopped working and controlled over the districts with fear. The 13th district was made of most of the New England states, It was in charge of the military, graphite mining, and nuclear weapons. They rebelled against the capitol. The rest of the districts joined. The war was lost and District 13 was destroyed by their own weapons. The Capitol forced the remaining Districts to send one young boy and girl to participate in the Hunger Games. It was a competition to the death. Each of the 24 district teens would fight for resources over 30 days. The objective is to kill others and survive. The real use of the games was entertainment for the rich Capitol citizens and eternal punishment for the "crimes" the districts committed against the Capitol. The series centers around Katniss Everdeen. Katniss is a girl from District 12 who gets selected for the Hunger Games. She spends the rest of the book trying to survive. 
The first book begins with Katniss making sacrifices to feed her family. She has to do this because District 12 is a very small, poor district. One day , the Capitol Peacekeepers, the police of Panem, come to District 12 and set up the raffle system for the Hunger Games. The adolescents of District 12 line up. Each gender forms it own line. The Head Peacekeeper pulls 2 names from the raffle. Peeta Mellark, a boy from the richer center of town, is the first chosen. The Head Peacekeeper reads out Katniss's sister Primrose's name. Katniss objects and volunteers to be in the games in her sisters place. 
The rights to the film adaptation of all parts of the trilogy were acquired by the Canadian media company Lionsgate Entertainment Corporation. Together with Lionsgate, director Nina Jacobson, president of Buena Vista Motion Pictures Group (the main film studio of The Walt Disney Company) worked on the first part.
