Part of The School of Life's Love series, Affairs delves into the question of affairs and why they happen so often

One in four people will be involved in an affair during their lifetime. Rather than condemning affairs as morally corrupt, this book helps us understand them.

Society tells us that affairs are unequivocally bad. Our culture casts those who engage in them as monsters, and their victims as deserving of unending sympathy. But most of us will be involved in an affair during our lifetimes. This book ventures beyond the cultural caricatures and provides psychological context for this entirely common occurrence. This book seeks to help us through affairs, offering couples a better understanding of each other's motivations and moods-and the practical tools needed to save a relationship.
