The Adventures of Don Roberto is a book of action, mystery, friendship and fun. Roberto is a gringo who meets Chapo, the son of a Mexican migrant worker, when his uncle brings Chapo's family from Mexico to work his cotton fields in West Texas. At the tender age of seven, Robert takes the Spanish version of his name. In his mind, the only thing he lacks to be a real Mexican is a Green Card. The boys are friends for life, and the story revolves around their antics when they are young and their adventures, together and separately on both sides of the border, as they become men. Roberto accidentally discovers an international drug smuggling operation and drags a reluctant Chapo into the middle of it. Things get serious when Chapo has to choose between the lives of his wife and children or the life of his friend.
