I was given this free review copy audio book at my request and have voluntarily left this review.
I would definitely recommend reading or listening to the first 2 books before this one. Not that you need it to follow what is going on (it’s a post apocalyptic story, after all) but I can see how it would make it more interesting to have the background knowledge about the survivors. The narration is very good and I have thoroughly enjoyed this whole series. On to book 4
