N.B. I received a free copy of this book via freeaudiobookcodes.com. It was the final entry in the series, but I’ve not read any of the others. It wasn’t bad, but it wasn’t great either. That just may be a combination of me not being a huge fan of the genre combined with this being the 4th entry in the series. I did enjoy the news sources after that showed the thoughts and reasoning behind the author’s choices in the story. As someone in cybersecurity, a lot of it rings true as a possibility.
