The Spirit That Possessed Harry Potter

Transported into the body of Harry Potter at the beginning of his third year, a modern-day fan finds herself with the chance to rewrite destiny. Armed with future knowledge and a playful disregard for canon, she navigates the magical world, befriending the infamous Sirius Black (in dog form) and disrupting the established timeline. Can she save those meant to die and outwit a Dark Lord, all while sharing a body with the bewildered Boy Who Lived?
You open your eyes. You are not on your couch, and your favorite corn nachos are gone. Instead, you find yourself in what looks like the Dursley's house, a cramped and unpleasant place. A voice echoes in your mind – Harry Potter's voice, confused and panicked. You quickly realize you've been transported into his body at the beginning of his third year. Stepping out of the house, you encounter a large, shaggy black dog, instantly recognizable as Sirius Black in his Animagus form.
