I really enjoy listening to this series it has great character development much action and in this book a lot of military action as well as zombies. The main characters are Sidney Bannister, Jake Murphy, Vern Campbell (a favorite in this one) his granddaughters Sally and Katie, Carmen and her children Miguel and Patricia, Mark Mullins and Sidney’s newborn Lincoln. Both North Korea and Iran have come to the US. The Iranians have taken over the airport and heading to the farmhouse as well as zombies while Jake was taken back into his army as he was AWOL. It is a fast paced book and highly recommend this series from the start to get full effect of the characters as they proceed in each of the books. Cannot wait for next book keep them coming . I was given this free review copy audiobook at my request and have voluntarily left this review. Thank you
