This is a very well-written book from beginning to end. The author has obviously put prolific effort and research into the background needed to write about the drug cartels in Mexico. This is an outstanding addition to the series. It has a complete and well-written ending. The novel can be read as a stand-alone book, but I recommend that you read the series because every book is well-written and gives a bigger picture into the characters involved in the whole on-going story.
