The Hunger Games Idears

These are some ideas for some hunger games books, if you have any ideas please fill free to post.
One of the ideas I had is, what if it was after Mocking jay and it was about Prim. I know that she died but what they never found her body. And some one save her, and she ends up in a place name Foundera, a place were they live like we do they have christmas and live like we do. And Prim has lost her merrory. And stay's with the Sams family, for a frue years. until she starts to remember. Then she has to get back to Panam, and is trained by Hamlit a member of the sams family and her best friend. the way to Panam will be hard but with the help of new friends can Prim make it back.
