A silent killer has taken the life of the beloved high school softball coach in the quiet Navajo community of Black Horse. Soon, Darcy Redbird's tribal sister, Susan Little Bull is arrested for the murder of her married boyfriend. If Darcy hadn't been run off the road by a Shadow man, she could have provided an alibi for her sister. In trying to prove Susan innocent, Darcy's investigation is hampered by the FBI insisting the killer has been arrested, her boyfriend and former policeman, Raymond Tsosie and continued appearances from the Shadow Man. Her perception of the Native spirits is tested and her life endangered as she discovers secrets and lies among the blowing dust and tumbleweeds.
