So, I'm basically having this huge headcanon for the NextGen of Harry Potter. It's a bit AU, mostly because I'm still not over the deaths of Sirius, Remus and Tonks, so I totally made up my own universe where Sirius reunites with his ex-girlfriend Mary MacDonald during OotP, who saves him during the battle in the DoM, which is why he is there during the battle of Hogwarts to save Remus and Tonks. They all get kind of adopted by Molly so that it's basically one huge family, what was hinted at during the epilogue of DH. Like I said, AU, but I like it way better this way.

This story is going to be a series of one-shots surrounding the NextGen kids during their time in Hogwarts. I've read a lot of NextGen fics, so there is a possibility I kind of subconsciously stole other peoples headcanons. If that happened and you recognize something I'm sorry I didn't credit you.
