I know about the fantasticfiction website that tells the order of an author's work but it doesn't tell if a series needs to be read in order or not, at least in any way I can determine. Is there a resource that tells if a series has to be read in order to make sense? I've got a couple of Brad Thor pb's that are his 3rd and 5th books. I don't want to start one if his stuff needs to be read sequentially. W.E.B.Griffin is one that comes to mind that does rely more on prior work for full understanding of what's going on and Vince Flynn as one that pulls minimally from prior work. I'd like to be able to tell that about any auther prior to purchasing anything as well as when evaluating stuff on my shelves for 'suspects'. Thanks for any input on this.
