After losing part of his left leg, former bodyguard Joshua Duffy takes a job as a mall cop to support his family, but runs into an old friend who has a much more intriguing job offer, to join a mission into the Sierra Madre mountains in Mexico to broker peace between the drug cartels in the region.

Joshua Duffy was a Close Protection Agent-- a professional bodyguard, and one of the world's elite operatives... until his last mission in Lebanon. He got his primary out alive, but the cost was the loss of Josh's lower left leg. There's not much call for a high-end guardian with such an injury, so now Josh is supporting his family working as a mall cop in Virginia. A lucky run-in reunites Josh with an old comrade who offers him a shot at a lucrative job: the UN is sending a peace mission into the Sierra Madre mountains in Mexico-- an area so dangerous it's known as Espinazo del Diablo, the Devil's Spine. Just two problems: Only a fool would think they could broker peace between the homicidal drug cartels in the region, and only a madman would sign on to keep those fools alive. - adapted from back cover
