I've always wanted to read Riker/Beverly fic. Not angsty OTP fic so much as an ill-advised hook-up between friends whose canon love interests both seem so frickin' high-maintainance. Always thought they'd be cute.
There's a great story called Friends and Crewmates
in an Idylls
zine (put out by Orion Press, if you wanted to track it down). It's set between Generations and First Contact. Not much of a plot, really, but it show a nice, friendly fling between Bev and Will (until Picard turns up unexpectedly one morning!)
