Retired border agent Grady Matthews has gone missing in Southwest Texas, might be dead. His old friend and Border Patrol compatriot Ryan Shaw is determined to find out what happened to him in this vivid tale of crime, deception and mystery along the border between the United States and Mexico written by a retired federal agent. In his search, Shaw descends into a canyon once used by smugglers that leads to Mexico. And encounters a lovely and spicy young Mexican woman who could possibly lead him to the answer he is determined to get. Along the way he comes across a drug-running operation about to smuggle 15 tons of cocaine into the United States the old-fashioned way: via a workhorse pack train through the canyon. To try to learn Grady's fate, Ryan gets himself hired on as a wrangler with the pack train. As this adventure unfolds, he must operate outside the law and his authority, evade detection of his border agent status by the traffickers, avoid tipping off Mexican authorities as well his own agency and other lawmen north of the border, and try not to be tempted into trouble by the bonita senorita. "Border Canyon" is the first book in the Border Agent Mystery series written by Ray Summers, whose three-decades career as a Border Patrol, Customs and DEA lawman in Texas, Arizona and New Mexico imbue the tale with a winning realism. It's an engaging narrative that beckons readers along into the borderlands with compelling twists and turns, puzzling questions and surprises along the way to its dramatic conclusion.
