Excellent first book in this series. A little different slant on the apocalypse and it works! Dan doesn’t have a 5 star general for a brother or cousins that just so happen to be Seal Team 6. He’s not the manager of a Walmart regional warehouse with the only set of keys to the door nor does he own a gun store. He’s just a run of the mill 50 something office worker a long way from home helping out a life long buddy. A situation any of us can easily imagine. The characters are all easily believable and there aren’t so many that you can’t keep up with who’s who. All in all, I couldn’t stop listening and can’t wait for book 2 to see where the story is going.
