“She was never supposed to be my sister!” I burst out, my head falling back against the wall as venomous tears drench my eyes. My chest caves in, my ribs burn, my breath hitches. “And it’s not fair. It’s not fucking fair,” I chant, broken and hopeless. “She was supposed to be Theo’s sister and we were going to grow up together as neighbors. I would’ve just been a regular boy who had a crush on a regular girl, and that boy would have fallen in love with that girl the right way.”
