A beautiful, widowed Native American woman, Marlo Wren Wright, is found tortured and brutally murdered in the den of her Cave Creek ranch in Arizona. Because of the horrendous manner in which she was tortured, the detective in charge of the investigation, Keith Haines, speculates that the woman may have been involved in drug dealing. For months, law enforcement had been conducting surveillance in that immediate location working to expose a drug cartel that was headquartered in Mexico.
However, Beth Wright, the murdered woman's sister-in-law, an interior designer from a prestigious firm in Chicago, Illinois, vehemently disputes the detective's theory. Along with the help of Auntie Haines, a feisty, pipe smoking, octogenarian, who operates the finest bed and breakfast in Cave Creek, Beth seeks to uncover the secret past of her murdered sister-in-law. Their journey has many twists and turns as the two women follow a dangerous path that takes them from Phoenix to Sedona, ending at an abandoned cabin hidden in the woods near Show Low. It is here that Beth must face her own mortality and fight for her life as she discovers the meaning of The Other Half Of A Broken Heart.
