Written by Peggy Layton, Emergency Food Storage and Survival Handbook outlines a timely and practical six-step plan for storing a three-month reserve of food, water, and other required survival supplies. This book is perfect for the millions of families who are currently re-examining their preparedness level or looking to establish a prepping program. In effect, this book picks up where Food storage 101 left off as it contains details regarding more advanced preparations, where Food Storage 101 is more geared toward begining preppers. With that said, you do not need both books. The fundamental information discussed in Food Storage 101 can be found in this book as well.
