When My Fake Sister Slandered Me, My Curse Made It All Come True

I was born with a curse. Whoever I doom dies exactly as I say. When I was five, I told my kidnapper he'd be crushed by a truck. A semi flattened him seconds later. So I learned to stay silent. Until my adopted sister Lydia framed me for spreading rumors that she slept with a client and caught syphilis. My family locked me in my room for seven days without food. My fiancé ripped off my heirloom necklace and gave it to her. They demanded I apologize on my knees. I smiled and opened my mouth. Everything I "rumored" about Lydia? It all started coming true. Every. Single. Word.
