Zack Tolliver, FBI Canaan's Secret, Book 6, (Paperback)

A murder, Mormon mysteries, and a cave full of bones. Zack Tolliver left the Federal Bureau of Investigation to be with his family but when his niece is threatened in the aftermath of the horrific murder of a high school classmate, Zack responds. He learns clues may reside in old bones in a hidden cave on the summit of Canaan Mountain. There is another murder. Some powerful force doesn't want the bones exposed. Zack begins to unravel a conspiracy which potentially involves activist ranchers, the local sheriff's department, Mormon fundamentalists, high-powered state politicians, and secrets carefully guarded for over a hundred years.
