From the award-winning author of Hearts of the Missing and The Third Warrior SPIRIT DAUGHTERS A treasure beyond value. Her mother's life on the line. When a murder victim falls out of a closet at Police Sergeant Nicky Matthews' feet, her investigation leads her to a powerful tribal fertility medicine. What Nicky keeps secret is this medicine was once at the center of her father's scientific research. He'd isolated the single most-important compound in a fertility treatment worth a fortune ... and worth killing for. But when her father vanished, the identity and location of the plant that produced this compound was lost. Or was it? Nicky's archeologist mother may hold the key to the plant's rediscovery which makes her the target of the desperate killers. Nicky insists her mother stay away from the Fire-Sky Pueblo. Instead, she barges back into her daughter's life, determined to help Nicky solve the murder, and heal their contentious relationship. But her mother's return is the opening the killers needed. No way Nicky is ever going to let anyone hurt her mom, even if it means tracking the murderers into the New Mexico high country in the depths of winter. Will Nicky bring the killers to justice? Or just make them disappear?
