Changing the future

The summoning

James and lily potter are a complicated couple since Halloween in 2001 lily potter changed she became a power and fame-greedy person who forgot about her son and husband who loves so much seeing her like this James lost all the love he have for her he was just with her only for harry to have a mother he at least has his friends Sirius and Remus lupin-black who are family to him as he is the godfather for their son teddy and today is a very sad day for the three friends as they miss their little sister James cousin samaira Peverell who is godmother and aunt to harry  she went missing 6 months before the Halloween 2001 as her parents found dead James was devastated when he found his uncle Damon and anut Avantika dead in their manor and all believed that samaira is dead but not these three and harry they still believe she is alive but their hope is getting lost as it's been 16 years since she went missing and lily always snarks and laughs at him for searching a dead girl he always suspect that lily did not like her but she has no say in it as samaira is important to him as harry is.

Today was the day he sat in the room with Padfoot and Remus it's camera's old room whenever since she came to the manor he will always have this room for her remembering how much fun they used to have with her James felt tears in his face to see he is crying Sirius is just sitting with Remus with nub feeling as it hurts even to think about her because they all are the soul bounded brother and sisters they four are and then a bright yellow light blinded them for a moment and when the light cleared there was a paper floating James first check if there are any spells on it seeing none he took it and started to read it out as Padfoot and Remus should also listen and lily enter the room asking

"what the hell is going on with here?"

Sirius smiles fakely saying "if you shut up we would know"

they both glare at each other before lily can reply James starts to read

" Dear potters,
