PROLOGUE A FAMILIAR FACE I watched the two teenagers sitting together outside the Coffee Cat Café on a sunny Saturday morning. They leaned toward each other, their voices low and almost intimate, their bodies close but not touching. Most people probably thought they were a couple—a really attractive couple. The boy had high cheekbones and a lean, athletic build. His blue-and-green striped polo shirt brought out the green flecks in his hazel eyes. He was movie-star hot. But maybe I was just biased: Thayer Vega was my boyfriend, after all. Or at least he was before I died. The girl next to him looked exactly like I did, back when I had a body. Her bright blue eyes were lined with my velvety chocolate liner, and her light brown hair spilled down her back in thick waves just like mine used to. She was wearing a gray cashmere sweater and dark-wash skinny jeans from my closet. She answered to my name, and when a tear streaked down her cheek, my boyfriend leaned over to hug her. Instantly, I felt the ghost of my heart constrict. I should have been used to this by now: living a bodiless existence as a dead girl, floating around like a plastic bag behind my long-lost twin, Emma, watching her inhabit my life, sleep in my bedroom, and talk to the boyfriend I’d never get to kiss again.
