Who doesn't dream of being loved dangerously, thrillingly free from the tethers of restraint? It's a question journalist and author Kate Legge asked after the discovery of her husband's affairs. He was a high-powered media CEO, and she was a veteran journalist who was assured the infidelity was singular (more were to be discovered on the home PC).

Having tried (and failed) to keep the marriage going, Kate started to write about it, only to discover infidelities spanning four generations on his side of the family. The resulting book, Infidelity and Other Affairs asks why some choose restraint, while others choose wild abandon.
