All nine books are great. This is the second time through the first 9 books. Since book 10 came out and it has been awhile since I listened to Slow burn I like to start from the beginning. I remembered I really liked this series and now I remember why. It’s so good!!! I have over 1,700 books in my audible library,in every genre. Bobby Adair’s imagination and wit, along with Phil Thron voice acting skills is the perfect combination for a great series, If you like post apocalyptic genres with awesome and funny main characters that get in and out of one heroine situation after another. You’ll love Zed and Murphy as they banter together while fighting off man eating Zombies. Never a dull moment, not all fighting but high tension while Zed comes up with crazy rescue attempts and many hair raising adventures. I could go on and on . Plus 9 books for one credit!!!! I paid a credit per book until they came up with the box set. I was happy to do so. I think 1 credit for all these books is too cheap. I would have gladly paid more for all the hours of entertainment.Thank you Mr Bobby Adair and Phil Thron for your wonderful series. I’ll buy any future books you two do together, especially with zed and Murphy as your protagonists
