At a suburban barbecue one afternoon, a man slaps an unruly 3-year-old boy. The boy is not his son. It is a single act of violence, but this one slap reverberates through the lives of everyone who witnesses it happen. In his controversial, award-winning novel, Christos Tsiolkas presents an apparently harmless domestic incident as seen from eight very different perspectives. The result is an unflinching interrogation of our lives today; of the modern family and domestic life in the twenty-first century.
