One of the best thrillers I have ever read. Making it more so is the fact that it is a true story based on the life of a DEA agent who risked his life in the jungles of Mexico, Colombia, Bolivia, Brazil, and other countries in a life and death struggle with the world's most treacherous and vicious drug traffickers. He was fortunate to survive these encounters to tell his story. He ran to where the brave dare not go. Truly amazing.
