Chloe Newcombe swapped her job as a New York investigator for the solitude of the Arizona desert. Now she has a full life and the more rewarding job of helping witnesses and survivors of crimes and accidents. When a bookmobile librarian is found riddled with bullets, Chloe is braced for the worst but not for the shock of actually knowing the victim. Erica Hill was once a good friend of Chloe's late brother, and, driven by guilt for not keeping in touch, Chloe combs the hot Arizona desert for clues. There's a nosy defence lawyer to question as well as Erica's teenage son and her jealous sister. What she discovers is a secret so dark that it threatens to crash and burn everyone who knew Erica...including Chloe.
