El Narco: Inside Mexico's Criminal Insurgency is a non-fiction book of the Mexican Drug War written by Ioan Grillo. In El Narco, Grillo takes a close look at the Mexican drug trade, starting with the term "El Narco", which has come to represent the vast, faceless criminal network of drug traffickers who cast a murderous shadow over Mexico. The book covers the frontline of the Mexican Drug War. It seeks to trace the origins of the illegal drug trade in Mexico, the recent escalation of violence, the human cost of the drug trade and organized crime in the country. The book takes a critical stance on the unsuccessful efforts made by the Mexican government and the United States to confront the violence and its causes.
