This book is one of the two newer books in the Killing Series. The focus of this book is obviously about the global war on terror, with a beginning point of the September 11, 2001 attacks in the United States. Obviously, terror groups have been around much longer than that, but that is the jumping off point for this book. The book is written with a focus on facts, but it is written somewhat like a novel with the descriptive detail, making it easy to read and not boring. It is also around 300 pages, so pretty quick to get through.

I checked this book out at the library, because I was given the entire set for Christmas one year and didn't want to buy the two newest ones. I know that Bill O'Reilly is a controversial figure, and I probably say that in every review that I do about this series, but I do genuinely like this series of books. I do not like most, if not all, of the things that the author has said and done publicly, but I do believe in reading what you want and taking what you read with a grain of salt. I did learn a decent amount of information about ISIS that I did not know, as well as a few other things, so the book was not a waste for me. If you are a reader of this series, you will probably like the book. I did appreciate that fact that politics were largely left out of this book, because we can all use a short break from the nonsense going on around here politically.
