Just after Louise DeSalvo gave birth to her first child, her husband confessed that he was having an affair. After surviving the crisis in her marriage, she began to read and write about adultery to explore the question of why people cheat. The result is this fun and compassionate book that draws upon the lives and works of literary figures such as Edith Wharton, Virginia Woolf, and Henry Miller to offer a transforming understanding of infidelity and marriage.
