Since the attacks of 9/11, the United States has steadily ramped up security along the US-Mexico border, transforming America's legendary Southwest into a frontier of fear. Veteran journalist Peter Eichstaedt roams this fabled region from Tucson, Arizona, to El Paso, Texas, bringing readers face-to-face with the victims, power players, and personalities that have riveted US attention on border security. By exploring the illicit paths of guns, money, drugs, and people as they flow back and forth across the US-Mexico border, Eichstaedt sheds light on the policies that contribute significantly to violence, abuse, and death—what most see as only Mexico's problems. He shares the eye-opening stories of migrants, desperate for work or to be reunited with family, who risk arrest and deportation by attempting to cross multiple times; accompanies the border patrol on a nighttime ride as immigrants are caught, then follows them through the system as they are jailed and deported; talks to humanitarians who are technically breaking the law by transporting lost, dehydrated migrants; and spends time with a Mexican coffee-growing cooperative whose fair-pay ethos eliminates the need for its growers to look to the US for a decent wage. Presenting humane alternatives to fear and steel fences and offering solutions to the immigration crisis,The Dangerous DivideexploresAmerica's tortured relations with Mexico, ultimately focusing on hopeful measures and providing a rational and workable way out of the border and immigration problem.
