THE POTTER PARADOX

(Oc story X Hogwarts Fanfic)

"I didn't come back to save the world. I came back to save him. If the world burns in the process? At least I'll be warm."
Krystal Potter was the 'Rare Potter'-tan skin, midnight hair, and eyes that had seen too many lifetimes. As a seasoned Auror, she had survived a war, but she couldn't survive the peace. After three failed marriages and a heart shattered by the ghost of her childhood best friend, Krystal is done playing by the rules.
When a broken, ancient Time-Turner tastes her blood, the universe glitches.
Krystal doesn't wake up as a wide-eyed eleven-year-old. She wakes up in her third year at Hogwarts-the year before the Yule Ball, the year the shadows start to crawl.
But this isn't the Krystal they remember. She's louder, sharper, and dangerously bored. With the mind of a lethal hunter trapped in the body of a fourteen-year-old, she knows every secret, every betrayal, and every death before it happens.
She isn't interested in being a hero. She's interested in her own version of justice. She's here to play a game where she already knows the ending-and this time, she's the one holding the cards.
Will she save the boy who holds her heart? Or will her selfish pursuit of happiness tear the timeline apart?
