I have really been enjoying this series. I want to start out with the morality rating PG-13 to R – this series does have some graphic violence throughout and bad language, although I will say that the amount of bad language lessened in this one compared to book 3 (which I was completely grateful for, there were only a handful of f-bombs in this one). These are not stand alone books, you really need to read from the beginning. I don’t want to give anything away, so my review may come off a bit vague. Book four picks up right where three left off… he’s on the run again trying to find his family and runs into new surprises and more trouble. The author does a fantastic job of keeping the story moving and me so wrapped up in it that I can’t put it down. Be ready to order book five when you get this book because it leaves off on the most horrible cliffhanger. If you like adventure and the post-apocalyptic style books then you’ll love this one. The narrator is a ton of fun to listen to and does a great job with the voices and acting.

I was given this free review copy audiobook at my request and have voluntarily left this review.
