Query: Excellent survivalist novel.

This book, a novel of survival, is a fine companion boot to the more do-it-yourself oriented "How to survive the end of the world as we know it" by the same author.The novel is well written, abiet sometimes more detailed in the specifics of survival methodology that is necessary for the story line, However, it is chillingly plausible in both the events and direction that the country could be led if the national infrastructure was broken for any reason.The book is well worth the read, even if your optimism precludes the possiblity that disease, inflation, subtrafuge, or invasion could undermine the social,moral,technical or financial fabric of the nation to the point of non-functionality.
