Bureau of Land Management agent Jamaica Wild has always been fascinated by Los Penitentes, a secret, ancient religious group that reenacts Jesus' crucifixion and practices excessive penance. And a recent, dramatic death she witnesses in the Gorge seems to be part of their rituals. But a haunted priest warns Jamaica not to investigate too closely. Too many strange things are happening to let this go. And when someone makes an attempt on her life, Jamaica sets out on a fact-finding mission that could send her over the edge.
