All I can think of the next Gen Harry Potter children going back in time to see their parents. I have a Harry Potter Imagines book with all generations. I wrote 2 chapters for the TimeTurner there, but I decided since it's the only thing I can think of to write I would give it it's own book instead. It was actually only supposed to have one part and the first part finished with them back in the future, but it's like they have a thing for going back to the past to see their parents over and over again, even though they can see their parents in the future, Except maybe Teddy, but that's it. Your Parents are Oliver Wood and Katie Bell. You have a twin brother named Oliver Wood (His middle name is Benjamin).
