I read this story a while back and have been looking for it. I was very invested in it and it drives me crazy to not know the ending. I lost the name of it when I broke my old phone.
harry potter fanfiction*
Harry,Ron,and hermione are transported to an alternative timeline. They are sent there after trying to destroy Hufflepuff's cup.
In this story it is Remus/lily but they cannot have children. Draco and Neville are best friends. James is a jerk that is not majorly involved in the story. Sirius and Snape are friends who tease/argue all the time. I am 99% sure it would be rated Mature. It should have at least 20 chapters and be a pretty long story.
If you could leave a review with anything you might know that would be so helpful.️
