I just read this book from cover to cover this weekend and cannot stop thinking about it.  It is pretty scary.  The premise of the book:  What if something happened (EMP- it explains it in the book) and no electronic worked anywhere?  It is a pretty frightening scenario, and for sure, had me thinking.  I tend to read big disaster type of books, if that is not your thing, you won't like it.  Just thought I would post in case you were looking for a new book to read/listen to.  It isn't a new book, I just stumbled across it at a lawn sale.
