Muggle in Hogwarts

One moment you're a regular fourteen-year-old, obsessed with the Harry Potter books and cosplaying at King's Cross Station. The next, you're barreling through a brick wall and landing face-first at the real Platform 9 3/4, surrounded by genuine witches and wizards. Now stuck in a world you only knew from fiction, and even sorted into a House you never expected, you must navigate the dangerous and magical halls of Hogwarts while trying to keep your Muggle identity a secret. Can you survive the Triwizard Tournament and the looming darkness, armed only with book knowledge?
The hustle and bustle of King's Cross Station faded into a blur as you ran towards the brick wall between platforms 9 and 10, a fake wand clutched in your hand. It was just for a video, a silly recreation of a scene from your favorite books, the Harry Potter series. But instead of hitting a solid wall, you felt yourself pass through, the air shifting and the sounds of a different world filling your ears.
You stumbled, falling onto a platform teeming with genuine witches and wizards. Owls hooted, steam billowed from a scarlet train labeled 'Hogwarts Express', and a rude blond boy was yelling at you. This wasn't a dream. This was real. And you, a Muggle, were somehow at Platform 9 3/4.
