With a baby on the way, sudden deaths in the family from which to recover, a re-election campaign looming, and a daughter heading off for college, Cochise County Sheriff Joanna Brady has her hands full when a puzzling new case hits her department, demanding every resource she has at her disposal. Two women have fallen to their deaths from a small nearby peak, referred to by Bisbee locals as Geronimo. What's the connection between these two women? Is this a case of murder/suicide or is it a double homicide? And if someone else is responsible, is it possible that the perpetrator may, even now, be on the hunt for another victim?

Juggling her pregnancy, family deaths, her daughter's imminent departure for college, and a reelection campaign, Cochise County Sheriff Joanna Brady investigates two suspicious falling deaths that may be the work of a serial killer.
