\'Abbe Mouret\'s Transgression\' is the fifth novel in the \'Les Rougon-Marquart\' cycle, following the overly zealous priest Serge Mouret in his search for spiritual purity. He lives in a near constant state of prayer, neglecting his worldly needs until he becomes gravely ill and begins to suffer from Amnesia. In this state of amnesia he forgets his priestly vows, becoming a whole other person and experiencing the world in a completely new and profound way. This novel draws numerous biblical parallels, exploring the meaning of innocence and sin as well as the relationship between the Church and Nature. It is an incredibly compelling and thoughtful read with truly beautiful moments thanks to the strength of it\'s cast of characters.
