Tatum Christine - Obsessive Sister Makes You Cheat _top_

If you are looking for a story that will make your skin crawl, your heart race, and your morals question themselves, this is the dark rabbit hole waiting for you. Just remember: In her world, the sister doesn't take no for an answer. And that is exactly why you can't stop listening.

One day, Rachel's prodding became too much for Tatum. Feeling trapped and frustrated, Tatum made a mistake that would change everything...

Unlike a stranger, Tatum is already inside the protagonist’s life. She has access to phones, private moments, family history, and emotional vulnerabilities. Her obsession isn't a distant threat; it's a slow poison administered at the dinner table.
