A great series right now I'm reading, it has way to many books to count... I want to say it's around 12+ books.

The story is a fictional idea of what might happen to the world after Jesus comes back during the rapture as foretold in the Bible. It follows two characters: Rayford Steele, an Airline Pilot and Buck Williams, a world renown journalist. The story starts In Medias Res, right before the rapture happens, these are quick and very interesting reads.
