Part memoir, part sociological study, IS MONOGAMY DEAD? highlights the huge disparities in how people define a 'relationship' and what constitutes 'cheating'. Rosie draws on her own experience and interviews with dozens of people, gay and straight, male and female, to discover that, even if we think of ourselves as 'monogamous', we might not be truly faithful in everyone's eyes. A brilliant mix of humour, heartache and science, this is a book for anyone interested in human motivation and behaviour, relationships and sexuality.
