Father Duncan MacAskill has spent most of his priesthood as the "Exorcist' --an enforcer employed by his bishop to discipline wayward priests and suppress potential scandal. He knows all of the devious ways that lonely priests persuade themselves that their needs trump their vows, but he's about to be sorely tested himself.

While sequestered by his bishop in a small rural parish to avoid an impending public controversy, Duncan must confront the consequences of past cover-ups and the suppression of his own human needs. Pushed to the breaking point by loneliness, tragedy, and sudden self-knowledge, Duncan discovers how hidden obsessions and guilty secrets either find their way to the light of understanding or poison any chance we have for love and spiritual peace.
