“This is the first serious scholarly study on electrification in the Andes and will be welcomed by historians of Peru and Latin Americanists more broadly. Its questions about modernization, social change, and the state raise important themes for historians working on other Latin American nations. The book’s clear style, innovative approach, and focus on a century of change will make it appealing to assign to graduate students and-especially important-to undergraduate students.”-Mark Rice, author of Making Machu Picchu: The Politics of Tourism in Twentieth-Century Peru
