i found this book

[NorthernRaider]

Yes I believe Left Behind is one of a series of fictional novels that tells the tale of the people who are left behind after the religious event called Judgement day orTribulation or Rapture IIRC, I find any book with a religous influence usually gets used as toilet paper when I'm out camping like J W Rawles last book Survivors which was supposed to be a story about a post apoc survivors fighting his way home, but it turned out to be a piece of garbage used by Rawles to mention religion every other page.
