A Tucson vacation morphs into terror when two teenage girls and their aunt vanish. When the girls' desperate parents beg their friend and Connecticut investigative journalist Carol Rossi for help, Rossi can't refuse. She leaves her infant daughter, police detective husband, and treasured farm and animal sanctuary to lead the hunt through the desert. It's 1985, and Rossi is chasing down a new kind of danger: the serial killer. When the Tucson police aren't interested in her theories, Rossi acts alone before the killer can strike again.
