Into thin air – a toby parkman novel

When someone snatches a child in the charge of 14-year-old babysitter Essie Beal, Bancroft, California Detective Toby Parkman is determined to work every angle, beginning with Essie. Then the case spins into a nightmare--the guilt-ridden Essie flees across the Bay to take refuge in the maze of San Francisco's streets. Toby's best chance of finding the boy is to locate Essie, who may be in more danger than she knows.
