Black thunder
(Book)

"A construction crew found the first body. The cops found three more, in a cluster that lay on both sides of the border of the Navajo Reservation. Because some of the bodies were buried outside the Rez, Navajo Police Special Investigator Ella Clah and her team must work a delicate joint investigation with the New Mexico police. Unless they can find what connects these victims, someone else may soon be killed. Ella's ability to concentrate is battered by worries about her teenage daughter, who has been skipping school, and her mother, who is cooking up a storm, a sure sign that trouble is brewing in the household."
