What happens in The Hunger Games?

It is set in future America. It is set in a family of Katniss, prim and the mother. Their father died when they were young in a coal mine explosion. There are annual Hunger Games- a game where 2 tributes are picked from each of the 12 districts to battle it out against the 24 other tributes to win. From district 12 (where it is set) a boy and a girl must be chosen. Primrose (prim) Everdeen is chosen alongside with Peeta Melark. Katniss Everdeen, prims sister, volunteered to take prims place. Peeta and Katniss are immediately sent of to the capitol to be trained  Haymitch, their coach has an idea for them to be 'lovebirds' so fans will like them and will sponsor them. Katniss has the nickname 'the girl on fire because on a live t.v. interview she wore a dress that caught fire when she spun around. She gained a lot of popularity which was helpful when it was time for the games to begin.

All 24 tributes were put out into a large dome and the games began. The contestants had to run to grab backpacks full of essentials to survive and weapons. Katniss grabs water purifiers, a coat, food, tools, weapons, and a sleeping bag. It seems that a lot of tributes are still alive after a few days, so the game makers decide something needs to be done. They set fire to the forest Katniss is hiding in . And she escapes, though she VERY BADLY burns her calf. She hides in a tree. Katniss pairs up with a young girl, Rue. They throw wasp nest (trackerjackers) on some of the tributes and kill Fox faceAnyway Katniss and rue go out to destroy some of the other tributes camps and while Katniss is gone for a second, rue gets stabbed by marvel (one of the tributes). Katniss dresses rue in a grave of flowers while rue slowly dies an excoriating painfull death. 

Katniss meets peeta. She finds that Peeta has been badly attacked by Cato and needs urgent medical help. They find a cave, and Katniss slowly nurses Peeta back to health. (They continue playing the lovebirds for the cameras and get many sponsors.) When it's just Katniss and peeta left, the announcer says the rules have changed, and only one can win.  As they are playing at being lovebirds, they trick the capitol into thinking they are so in love, that they would rather both die. They are about to eat poisonous berries and die together, when the capitol says they have both won!
