I have listened to over 500 books on Audible and this is the FIRST time I am writing a review. The narration was wonderful…kept me intrigued! 55hrs for 1 credit…WORTH IT!!! I’m not a zombie-end-of-the-world-virus fan, just an avid listener, but I enjoyed this series so much, I purchased Book 10. If you are on the fence about using your 1 credit and are browsing through these reviews…my advice is stop wasting your valuable time browsing and start listening to this post-apocalyptic epic that has a somewhat happy ending…yes, you read that right…a…happy…ending!
