I have read about food storage off and on for years and this is one of the best -- well-written and engaging. The initial suggestions for getting started on a rotating storage system are easy and doable for most people... no giant root cellar construction needed.  From Amazon Reviews

(Gardening for the Faint of Heart), Wheeler’s first book, is a delightful read, full of humour and down-to-earth advice.

Worrying about where one is going to get their next meal is never something one wants to have to deal with. "Food Security for the Faint of Heart: Keeping Your Larder Full in Lean Times" is a book about preparation when crisis hits. In this modern world, everyone takes the existence of the supermarket for granted and has enough food for about a week, two at most. Covering the skills one needs to stay fed when disaster hits such as preservation, foraging, rationing, and more, "Food Security for the Faint of Heart" is something to keep at hand in case the worst occurs.  From Amazon Reviews
