My reason to live. (Hunger Games Fanfiction)

Katniss didn't go to the games. Erika Angelfire volunteers for Primrose Everdeen, in an act of suicide, but when the guy she's been in love with gets chosen to go with her, she will do everything to save his life, but for Peeta, the survivor needs to be her. Together, they will create a whole love story so they can both survive. What will happen in the 74th anual Hunger Games? (The summary sucks, but please do read! It will be interesting, I swear)
