Here's an excerpt from Chapter 7 ("Tribulation and Patence")of my purposeful (gospel) Sci-fi (time travel) novel, where we see more of the efforts of the time travelers (who were pulled forward to their future and forced to fight in a senseless war) to escape their captors, aided by strange phenomena of nature, which phenomena you should readily recognize as the things pictured in the Book of Revelation at the start of the tribulation period. And By the way, this book is now available in Spanish, German and French as well as English.
