"In 1973, the American Indian Movement was a militant organization that had spread its influence across several reservations. After a standoff against federal authorities on the Pine Ridge Reservation in South Dakota, AIM's members went into hiding on other reservations." "Liz Plenty Horses was there during the Pine Ridge incident. Afterwards, she returned to the Wind River Reservation to help AIM members wanted by the FBI blend in with her people. But when one of them was shot to death by the police, Liz was accused of being an informant - and fled with her baby daughter, never to be seen again." "Now, the remains of a skeleton with a gunshot wound in the back of the skull have been discovered at the bottom of a remote ravine on the Wind River Reservation. The body was that of an Indian woman who was murdered sometime in 1973. When the police encounter a wall of silence that falls over the reservation, Arapaho attorney Vicky Holden and Father John O'Malley must unravel the truth - only to incite the malice of a killer from the past."--BOOK JACKET.
