Although the book is fiction it is filled with fact. Clinton McKinzie's book "Crossing The Line" tells of the Mexican drug influence along with the governments refusal to secure the borders. Mr. McKinzie was a prosecutor in Denver so he has first hand knowlege on illegals. I am an avid reader of at least two books a week and this is probably one of the best I have ever read. It really put the pieces together as to why there is so much resistence by the U.S. government to secure our borders and especially to stopping the drugs from entering our country.
