I was given a free review of this audiobook and have left this honest review voluntarily. I loved how the complete series was included! At the end of each book I wanted to hear more so it was great being able to hear it all. It’s a scary thought that anything like this could ever happen, but the unknown is what makes this book so good. Not knowing what could happen makes you consider the “what if” and wonder if things mentioned in this book could happen the way the author described. It was exciting, intense, action packed, thought provoking…altogether really good!
