I’ve had several people ask me about the popular Left Behind novels, written by Tim LaHaye and Jerry Jenkins. The series fictionalizes the book of Revelation into a fantastical end-times story, but it also brings up some serious questions of its validity and accuracy.  
I’d like to recommend a book I have found extremely helpful in deciphering this series: 
Reading Revelation Responsibly by Michael J. Gorman. 
Gorman addresses several hermeneutical (interpretative) issues with the series.
The series treats Revelation as a puzzle of future events. It claims to be a literal interpretation, but includes some events which are not found anywhere in Revelation, and it assumes we are living on the brink of rapture and tribulation, among other things.
