I just finished the most unqiue survival book I have ever read called Holding Your Ground. I purchased the paperback through Amazon for about $20. The book covers a topic I have never seen before - how to set up and defend a location like your house or farm. Some of the ideas are very good and several times I said to myself "why didn't I think of that?" It's a planning guide as well. You go to a webpage,Holding Your Ground | Prepper Website , and download a spreadsheet. As you go through first part of the book, you enter values into the spreadsheet and it determines the strengths and weaknesses in your plan and with your 'team'. Most of the concepts are low cost (important around here) and the primary focus is on hiding in plain sight. Another thing that was cool was none of the preparations would mess up my house or hurt its value. I have a whole shelf of army field guides and prepper books and this one ranks up there with the best of them.
