Who – or what – is killing members of the Navajo tribe? RESERVATIONS, the first book of the Jack Del Rio political mystery/thriller series, is set near Gallup, New Mexico, where the Navajo, Hopi and Zuni reservations lie adjacent. Three tribal leaders have been murdered – murdered in a fashion that suggests the deeds were carried out by COYOTE, a legendary supernatural evil trickster feared by many Native Americans.
