Prim is Katniss' 12-year-old sister. Prim takes after their mother, who has light hair and blue eyes. This reaping is her first, and Katniss has only allowed her to enter her name once into the drawing. Prim is the only person whom Katniss is certain she loves, and she does all she can to provide for and protect her sister, eventually sacrificing herself when, against all odds, Effie Trinket draws Prim's name at the reaping. When Katniss struggles to survive during the Games, she thinks about Prim and the promise she made to her that she would try her hardest to win. This promise gives her the strength she needs throughout the Games.
