Joshua Duffy is a Close Protection Agent -- a professional bodyguard -- and, as such, he's one of the world's elite operatives. That is he was until his last mission in Lebanon. Against all odds, Josh got his primary out alive, but the cost was high-the loss of Josh's lower left leg. There's not much call for a high-end guardian with such an injury. So, Josh has to support his family working as a mall cop in Virginia. For a man like Josh, this is purgatory on earth, but miracles can occur even in the suburbs. A lucky run-in reunites Josh with an old comrade who offers the desperate man 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.
