I purchased Armageddon before it was available on audiobook because I could not wait to hear what happens next. Im now anxiously awaitinf Book 3!! Ive read and enjoyed many of his series, but this storyline is different. It is gripping an unpredictable with connected characters in muliple locations each with their own plot. In my opinion, this is some of his best work. As I wait until April 22nd, I started the New Madrid series just to keep my mind off this family and Nuclear Winter.
