I have just mowed through the first five books of this series and as a post-apocalytic fan of many years as well as a huge Kevin Pierce fan, this is one of the best series that I have listened to. Mr. Ryan Schow rates up there with two of my other favorite authors; Mr. N.C. Reed and Mr. Keith C. Blackmore. Very well done, Mr. Schow and Mr. Pierce. I look forward to book six.
