This is a hunger games fan fic. It's been at least 4 years since the hunger games had been abolished and president snow killed. Katniss and Peter have settled down now ,but something isn't right about Peter. Ever since snow torturing him in the past ,Peter has become different, suffering from nightmares again and again about his torturing and having certain mood changes due to some venom still in him. Can peter overcome or will he start to become evil. Katniss also has a few problems of her own when Effie asks "if there having kids" of course they have tried but katniss doubts that she is pregnant ,
Will she find out that she Is carrying peters baby? And if so will she tell Peter?
Katniss and peter pov .
