This is a story of a boy raised in an extreme ultra-strict Protestant family, members of "the Exclusive Brethren". From an early age, James found he was at war with his family and the Brethren. Nothing that would be considered normal was acceptable. This book details his experiences growing up in this family, showing his struggles and confusions. It tells of the Brethren's involvement in his love affair and how the family put an end to his marriage because he had slept with his fiancee. It outlines his escape from the Brethren while he was working in a large London hospital. The book is a fascinating account of how other people live, depicting life in a hospital and the main character's work as a district nurse. The Exclusive Sinner is an exceptional story.
