Father Duncan MacAskill has spent most of his priesthood as the 'Exorcist' - an enforcer employed by his bishop to discipline wayward clergy and suppress potential scandal. Hidden in a small rural parish to avoid an impending public controversy, Duncan must now confront the consequences of his past. 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.Winner of the 2009 Giller Prize, Canada's Premier Literary Prize.
