Nelson calls this memoir by photographer and author Christa Parravani about the death of her identical twin sister due to drug abuse "a very emotional book." Parravani's sister Cara had been raped 10 years before her death and in some ways this memoir is the chronicle of her slow destruction ever after that event. The sisters were "very, very close and maybe a little bit competitive," says Nelson. "They shared a soul in a lot of ways."
