Would area of interest even matter? I think in a survival/shtf situation any how-to book has some need to it.
For example: This book was free for a limited time. It is still free to borrow for Prime members. Some of the links I would post, you would have to download in a day or two because the free time would expire. This is is very basic, very short, and a great easy 15 minute read, but great info for a beginner.
