rm | sci-fi fantasy lit column stuff

So as I work on the first intro article, I've been struck by a couple of ideas for future articles. One on great out-of-print stuff you should track down, and the other -- wait for it -- a Valentine's Day feature. Yes, that's right, the great (or completely compelling and utterly fucked up, to be more accurate) relationships in sci-fi and fantasy novels.

So far I've got a few on my nomination list (that is, some will make the piece and some won't) including Molly/Case from Neuromancer, Paul/Chani from Dune, Gentle/Pie from Imajica, Alec/Richard from Swordspoint, Phedre/Josclin from Kushiel's Dart, Asriel/Mrs. Coulter from HDM, Jodeau/Xas from The Vintner's Luck (this is the one most likely to get booted right now, as I'm using that book in the out-of-print piece).

But all of this speaks to my particualr biases of the moment. What am I forgetting? What haven't I read that I really should (I know, everything!)? Anyone got some f/f or poly ones for me to reference? I know they are in my brain somewhere, but they're not coming to the fore. As should be obvious from what's above, happily ever after not required. Also more hard sci-fi stuff welcome. I really like hard sci-fi, but I'm largely at a loss on it for this particular list (thank you, William Gibson for making me not look like a total pussy).
