Hi, Louise,
Yes, it does seem that the stories are getting more and more "AU." I'm guessing this is partly because things tend to go in trends, and partly because writers are searching for a premise that hasn't been done before. I'm pretty much open to anything that's well-written and grabs my attention.
I'm intrigued by the premise of J&E as a couple of "regular joe's" in a modern-day setting. Most notably, Mel and I have been having a lot of fun discussing "Camden Yards by debutante9 (Kumari) recently. In this fic, J&E have been best friends for 15 years and their families are very close, the wives are also best friends. When I first read this premise, I wasn't sure how the author was going to hande this - but she's done so brilliantly. I don't know that I would describe it as particularly heavy on plot, but very heavy on character development and loaded with beautiful, subtle symbolism, with a lot of depth.
"Going Home" by 1_of_one (Helen) is exquisite. Takes place in the present in Scotland, updates on "real time" holidays and has a beautiful blend of ancient Celtic mysticism. One chapter, "Lands of the North" takes place in 5000 BC where we meet Enniz and Jahhg.
Got to run for now - more good fics to recommend.
