I read a fair amount of dystopian and SHTF themed books and eventually ran across Mark Goodwin. The general theme of his books, which are also prepper based, are the prophesies of Revelations taken in a modern context. I've read Revelations before, but reading it in this context makes it easier to relate to that chapter of the Bible as well as other portions. It's really a very entertaining way to do some Bible study. I just finished the "The Days of Noah" and "The Days of Elijah" series which work their way through each step of Revelations. All of the others are set in the same sequence of events. They really have me thinking about my role as a Christian as well as helping me to evaluate my preps a bit better. Note: These books are not Divinely inspired writing and I'm certain there are folks that can find issues or would have different interpretations. They are, however, good stories that inspire Christian thought.
