I came across a great resource page with PDF downloads, for free, from a Calvary Chapel church near Houston, Texas and you’ll find a great eBook at this page “The Tribulation & The Church” by Chuck Smith which goes well as an overview pertaining to our current Revelation study. The website is: http://www.cclakehouston.org/eBOOKS.html.

There is also a great chapter in the eBook “Calvary Chapel Distinctives” called “The Rapture of The Church” and it was that chapter in that very book that turned my understanding of prophecy from leaning toward a post-trib view to committing to my now held pre-trib view.
