This series is well written and well read. I never once got bored with the storyline. I declined phone calls that came in during a tense part (which are frequent). The entirety of the book is believable, R.E. McDermott has obviously done tons of research. His description of locations and character development were exceptional without going too far and loosing you, the listener.
Give it a shot! It’s an incredible listen for only 1 credit.
