Delia Ironfoot hasn't practised archaeology in years owing to accusations of fraud and the subsequent loss of her university tenure. However her grandfather asks her to return to her native Navajo home and excavate a burial mound on his farm. But modern secrets are buried with these old bones and as Delia excavates, the threats excalate until her life, and those of her family, are threatened. Someone will do anything to keep those secrets buried - unless Delia can uncover who it is and why those bones are so precious.
