After Mockingjay, Always and Forever

Katniss and Peeta have been through more than anyone could ever imagine. They have seen loved ones die, witnessed countless acts of cruelty and have been subjected to an inordinate amount of pain, both physically and emotionally. After the fall of the capitol they were sent back to district 12 and expected to carry on as if nothing had happened. However there is a lot more to the rebel government than just the equality and strength they supposedly offer and the protection they claim to give. Will Katniss, Peeta and Haymitch be able to cut the rebels short before they become just as bad as the capitol ? Or will they stay out of the way and have to deal with the consequences ?
