There's some good stuff on bau_fic. Click on the reid/prentiss tag. I recommend anything by Fabrisse, and a story called "Four Eighths" just started posting the other day, I've read it on ff.net and it's good.

My fic begins here:

It's already completed, 40 chapters and 137,000 words (I know, I know). I'm posting one chapter per day, I'm up to chapter 19 now. Chapter 20 will go up tonight.

There's just so little R/P fic I feel like I want to spread the word.
