We live in a world laced with forms of political violence. Kristen Renwick Monroe's latest work develops an interesting social psychological account of the conduct of victims, perpetrators, and bystanders of the most extreme form of violence—genocide. It also employs an interesting narrative approach that contributes to broad methodological discussions in political science about the ways in which subjective experience can best be understood. We have thus invited a diverse group of political scientists and historians to comment on the book's analysis of political violence and on its broader approach to the study of politics.—Jeffrey C.
