This has to be the best fiction series I’ve ever read (listened to). I greatly appreciate Bobby Akart’s writing which is free from gratituous sexuality and has minimal foul language. I have all of his titles in my library and this series is the best yet. Much like a good print book I couldn’t quit listening until I finished each installment. His use of suspense and the weaving of plotlines keeps you coming back for more. This book series was completely believable and scary from a potential catastrophic perspective. I also like the way he uses a family for his key characters and their interactions. I couldn’t recommend this book any higher. Also greatly enjoy Kevin Pierce’s narration and tend to be disappointed now by others.
