At present, this is not a 'recommendations' page; I don't have the time to rank or comment specifically on each fic. I'm putting it up because I'm a crossover/AU junkie, and I spent a lot of time hunting for well written fics mixing it up in my favorite fandoms. This particular page contains the slash portion of the list I've compiled; I'm separating it from the gen/het portion as many fans choose only to read one or the other.

(Yes, I said SLASH. If non-heterosexual relationships are not your forte, please hit the Back button on your browser now. Most of these stories are heavy on the plot, not the romance, and many don't have any sex at all - I'm not a fan of PWP's - but all the same, it's in there, so consider yourself warned).

New links will be highlighted in red. If you find a broken link, please let me know! And feel free to let me know of any good crossover fic I've missed! I can't be everywhere.
