I learned a lot from this book and left with even more questions. There has been much discussion about how/when/where the world would end and what would happened. In this novel ( had to remind myself many times it is fiction) which is backed by many references to the bible, we learn that people just vaporized into thin air, leaving everything they were wearing and everyone behind with no clue as to what happen. Through the telling of three main characters we begin to see how they disappeared and what is coming. After reading this novel I need to check some things out and then begin the next volume in this saga.
