i’ve read many ‘fiction’ titles in this genre. Many are fanciful and entertaining if you simply like the doomsday apocalypse genre. Others, this work included, offer practical info and even references to actual outside sources and presents ideas on what is needed and how to survive should the worst come to pass. There is excellent survival info included and references to where to search for further reading and research if you truly wish to engage and survive in a possible worst case soco collapse scenario.
