Melissa Vogel's Frontier Life in Ancient Peru offers a new perspective on ancient Peruvian life and geopolitics during a pivotal period of Andean cultural transformation between AD 900 and AD 1300. Focusing on the frontier site of Cerro la Cruz in the Chao Valley (located on the northern border of the Casma polity), this volume richly details the role of cross-cutting social networks and the dynamics of shifting political boundaries in prehistoric north coast Peru.
