Join Ada readers at the Ada Public Library on Tuesday, Oct. 2 at 7 p.m. to discuss Skinwalkers by Tony Hillerman.

Navajo Tribal Police Officer Jim Chee and Lieutenant Joe Leaphorn investigate murders that lead them into spine-tingling and mystical world of Navajo witchcraft.

Three unsolved homicides and an attempt on Chee's life have left the Navajo Tribal Police baffled. Are the murders somehow connected, although they occurred 120 miles apart?

Or are they random acts of violence? Chee and Leaphorn's efforts to solve the seemingly unrelated individual crimes leave them with clues that point toward one suspect, in this suspenseful mystery.
