I volunteer
Katniss's father died in a mine explosion, and since then she's the one putting food on the table, hunting with a bow in the forbidden woods alongside her friend Gale Hawthorne. At the reaping for the 74th Hunger Games, Effie Trinket draws the name of 12-year-old Prim, the first year the girl is even eligible. Katniss shouts that she volunteers. The other tribute is Peeta Mellark, the baker's son who once tossed her a loaf of bread when her family was starving.
In the Capitol, mentor Haymitch Abernathy explains that nobody survives without sponsors. Stylist Cinna sends her out in the opening parade in a costume that bursts into flames, and she becomes the girl on fire. In his interview with Caesar Flickerman, Peeta says he's in love with her, and Katniss assumes it's strategy.
