8They Leave Their Kidneys in the Fields takes the reader on an ethnographic tour of the melon and corn harvesting fields of California's Central Valley to understand why farmworkers suffer heatstroke and chronic illness at rates higher than workers in any other industry. Through captivating accounts of the daily lives of a core group of farmworkers over nearly a decade, Sarah Bronwen Horton documents in startling detail how a tightly interwoven web of public policies and private interests creates exceptional and needless suffering.
