“My sister arrived trembling, br.uised, and begging me, ‘Don’t tell Dad anything.’ What she confessed about the woman living in her house chilled me to the bone. We looked so alike… that night I understood I could use my face to unmask the horror.”

I felt my jaw tighten as I watched a tear roll down her swollen cheek. “If Dad is home, she’s the perfect stepmother, but the moment he leaves, she calls me a parasite and a waste of space.”

“Did she do this to you?” I asked, my voice dropping to a dangerous whisper.

Geneve nodded, and then the floodgates opened as she described how Francine had pulled her hair and slammed her against the drywall. Once, she had slapped her so hard that Gen’s ear rang for forty-eight hours, and another time she was denied food because an ungrateful brat didn’t deserve to eat.

My sister had tried to talk to our father, but Francine would always start crying first, clinging to him and claiming Geneve was trying to sabotage their new family. “He told me I was trying to destroy his marriage,” my sister muttered, looking defeated. “And now he looks at me like I’m the villain in his story.”

I went to the bathroom so I wouldn’t lose my temper and break something in the living room. I stared at my reflection in the mirror and realized that for the first time, I didn’t just see myself; I saw Geneve’s pain looking back.

I walked back into the room with my heart feeling like it was on fire. “Go pack a small bag for me,” I told her firmly.

She looked at me with wide, confused eyes. “What are you talking about, Gabby?”

I took her shaking hands in mine and forced her to look at me. “Tonight, you stay here and pretend to be me, and I’m going back to that house as you.”

Geneve began shaking her head frantically, telling me I was insane and that Francine would hurt me too. But I couldn’t be stopped, so I took photos of every bruise on her body and sent them to a lawyer I knew.

I hid a small digital recorder inside the pocket of her oversized sweatshirt and pressed my apartment keys into her palm. “For once, that woman is going to mess with the daughter who knows how to fight back,” I said.

I drove to Scottsdale wearing Geneve’s clothes, including her worn-out sneakers and the simple gold band our father had given her for her birthday. Francine never really looked at Geneve, seeing only a target for her control rather than a person.

When I entered through the side garage door, the only light illuminating the house came from the kitchen. Francine was standing there waiting for me, looking as if she had been simmering in her own bitterness all evening.
