1. It's set in a post-apocalyptic world in the nation of Panem.

"The Hunger Games" is set in a dystopian/post-apocalyptic world in the nation of Panem, formerly North America, where the government holds absolute power over 12 relatively isolated states known as districts.

Every year, two children from each district are forced to fight for their lives in the Hunger Games, a televised battle-to-the-death where only one victor is left standing.

A girl and a boy are randomly selected in 12 "Reaping" ceremonies, to represent their district in the annual games, resulting in 24 total participants or "tributes." For some tributes, selection is an honor they train for, hoping to be selected. For others, it's an instant death sentence.

The games were established years earlier as a punishment for a rebellion led by the districts against the government, meant to be a reminder of the absolute power of the government. All in all, it makes for a form of twisted, reality TV-like entertainment for those in the nation's richest region, who are excused from sending their kids into the games, and escape the yearly heartbreak of the 23 families of the losing tributes who have to watch their young die. People living in the 12 districts are required to watch the games, to see their own fight for their lives.

2. The Capitol is the 1 percent.

The villainous President Snow governs over all of the districts from the power center of the Capitol, which is a shining city of luxury and excess and home to the nation's richest, most privileged citizens. (Think a futuristic Oz filled with narcissists). While residents of other districts are starving, the citizens in the Capitol binge on a never-ending supply of gourmet food. They also dye their skin, wear outrageous wigs, get plastic surgery for fun, and speak in strange accents.

For the Capitol citizens who don't send kids into the arena to fight in the treacherous games, the televised event is the ultimate in entertainment. (Take the media hype for the Super Bowl, the Oscars and the royal wedding combined). There's also a real culture clash as District 12 tributes Katniss Everdeen and Peeta Mellark meet the Capitol citizens and see how different they really are.

3. Katniss is a heroin and a real female role model.

Katniss Everdeen, played by actress Jennifer Lawrence of "Winter's Bone" fame, is the story's heroine. Katniss lives in District 12, the poorest of all the districts, which mines coal for the Capitol. Since her father's death in a tragic mine explosion, the 16-year-old has provided for her mother and younger sister, sneaking outside her district into the woods to hunt and put food on the table. When her 12-year-old sister, Primrose, is chosen as tribute at the Reaping, Katniss volunteers herself, saving her much weaker sister from meeting an inevitable death. From that moment, she has everyone rooting for her.

Before she goes into the arena, Katniss is made over into a fierce competitor. She's a character with true heart, guts and an unwavering moral compass.
