One thing that makes it stand out could be its unique take on character development. Maybe it gives a different backstory to a beloved character, like showing a more complex past for Hermione. It could also have an alternate plotline that diverges from the original books in an interesting way, for example, a different way of dealing with Voldemort.
Well, it might stand out because of its writing style. If the author uses a really vivid and descriptive style, it can bring the wizarding world to life in a new way. Also, it could introduce new magical elements or creatures that we haven't seen much in the official Harry Potter universe. This would add a fresh layer of excitement to the fanfiction.
The fanfiction 'A Different Life' could stand out due to its exploration of different relationships. It could show a different dynamic between Harry and his friends, perhaps a more strained relationship that then has to be mended. Or it might focus on a relationship that was only hinted at in the books, like a deeper connection between Neville and Luna. By delving into these different relationship aspects, it becomes a distinct and interesting read.
