Over the past two decades, increased criminal and state violence has profoundly transformed everyday life in Mexico. In , Ana Villarreal draws on two years of qualitative fieldwork conducted during a major turf war in Monterrey, Mexico to trace the far-reaching impact of fear and violence on social ties, daily practices, and everyday spaces. Villarreal brings two seemingly contradictory faces of fear into focus—its ability to both isolate and concentrate people and resources, deepening inequality. While all residents of one of Mexico's largest metropolises confronted new threats, the most privileged leveraged vastly unequal resources to spatially concentrate and defend one municipality more fiercely than the rest. Within this defended city, business, nightlife, and public space thrived at the expense of the greater metropolis. The book puts forth a new approach to the study of emotion and provides tangible evidence of how quickly fear worsens inequality beyond Mexico and the "war on drugs."
