I knew the exact moment I would stop being a daughter and become a villain. It was the Wednesday before Christmas, 7:38 in the evening, when I typed a single message into the family group chat. I had stood in my kitchen in Maplewood, Ohio, watching the snow start to fall outside the window, my hands still smelling of cinnamon from the coffee I’d made hours earlier. My husband David was in the living room, and I could hear him packing another box. The real estate agent had called that morning with the final signed offer.
