I only started reading fanfiction more recently. I had always loved Harry Potter so it was definitely fun to start reading remakes of the story that others had written. This recommendation is one of my absolute favorite Harry Potter fanfics and it's also complete so you don't have to be worried that you'll be left hanging.

To Be a SlytherinBy: Morgana Deryn
Like every sister, I love my brother no matter what. Even when he's an idiot. Even when he's in the spotlight and I'm forever waiting in the wings. That's life as Lorena Potter. Can't complain, really. At least I don't have a psychopath out for my head. OC-centric DracoXOC
Since the summary doesn't give many details basically it's a rework of the story with the idea that Harry had a twin sister. I loved her relationship (not romantic) with Tom Riddle aka Voldemort. I won't spoil the secret but it was well done. I also liked her take on everything that happened and what it was like to be a Slytherin and sometimes just how unfair it felt to be a Slytherin with people hating them for no reason. The relationship between her and Draco was well done too, it wasn't like they immediately liked each other, it's a relationship built over time and they literally are at each other's throats sometimes. After reading this I almost felt that it was better than the original.
