Prologue
The war had been over for about a month and nobody's life was the same. The Weasley's were mourning the loss of Fred Weasley, while Harry was learning how to deal with being the sole parent of Teddy Lupin. No one could remember how many funerals they had been too, but it was defiantly too many. Fred Weasley's was one of the hardest, along with the joint funeral of Tonks and Lupin.
Life was starting to move on, but everyone was still consumed with a mixture of grief and joy. They knew that this time Voldemort would not be back, but the cost of freedom had been huge.
Harry and Ron had decided to become Auror's and were forgoing the chance to complete their NEWTS after being offered the chance to join the Ministry without them. Hermione on the other hand, had agreed to take her NEWTS in a few weeks having, in typical Hermione fashion, continued her studies during the horcrux hunt. She had also decided to pursue a career in healing. She had seen so many people hurt by the war, physically and mentally, and she was determined to help them and the others who needed it.
Ron was having trouble understanding why Hermione wanted to be a healer not an auror. It had always been the three of them and he didn't see why it needed to change. Eventually Hermione sat him down and they had a heart to heart, which ended with both agreeing they were better as friends and to respect each other's careers and life choices. Of course this applied to Ron a little more than Hermione. Mrs Weasley had also taken some convincing that Ron and Hermione were not soul mates.
On the other side of the war, the losses and aftermath were being felt just as strongly. Many Death Eaters had died in the final battle including Lucius Malfoy. Several other key death eaters had been rounded up in the immediate aftermath including McNair and Goyle Senior and were presently in Azkaban awaiting trial.
One of the biggest shocks at the end of the war had been the discovery of Narcissa and Draco Malfoy locked in the basement of Malfoy Manor. It appeared they had been being held as prisoners. They were discovered malnourished and with obvious signs of dark magic. Both had been in St Mungo's recovering, whilst whispers and rumours of what had occurred at the Manor circled the wizarding world.
One thing was certain everyone's life was certainly different now the war was over and the changes were not over yet...
