Yeah, I quit reading the Foreigner series somewhere along the way, I think the story was becoming both too complicated and too forced--I could barely make myself skim through the last one I read.
Long series often seem to pick up too much baggage along the way and lose the momentum of the story.
Yeah, I probably am a book or more behind the latest as well. My reluctance has less to do with the excess baggage and more to do with my feeling that the plots are more contrived, Bren has become too powerful for the set up to make sense, and personally I would like a break from all of the unending political intrigue.
Edit: I just looked and I am SO WRONG! I am 10 books behind! I guess that comes in part from my getting a Kindle because I live an hour away from any bookstore which would carry anything like C.J. Cheeyh and now for several years getting almost all Kindle Unlimited books.
