I received an advance copy of this book, and I have to say that Ross and Kirkham have done it again. This series is setting the standard for post-apocalyptic fiction. The characters are well developed, and cross the spectrum from unprepared to very prepared and from good to evil. It is obvious that The authors are well versed in survival and tactics, so well in fact, that the story could be used as a learning tool. No one wants the world to end, but there is no excuse for being unprepared.
