Homicide: Life on the Streets. It's sad though, that the story was written before my time and the writer didn't leave updated contact info. So, Scott, wherever you are, your story rocks.

Laga, a good place to start for just about any fandom is Polyamorous Recs, run by our very own Shrift and Dana. They recommend hundreds of stories in dozens of fandoms, sorted by fandom & genre.

Another option is the LJ community crack_van, which is somewhat less reliable than Shrift and Dana, but still can have some great stuff.

I find a lot of good recs on Delicious, as well.

YAY

ooh thanks for the link!

edit: wow my first pick is so great. Curses! I'm hooked.

Woah, late back to this discussion.

But I'm balking a bit at dismissing this sewing-together as self-congratulatory timewasting.

I think that two things are going on here.

One, I've read (or started reading; perhaps I should have known better) rather a lot of crossovers where the sewing-together was overlong, unconvincing, and delayed our introductions to the characters. If the sewing-together works, that's great; but I think a fair number of bad crossover stories could be lifted to moderate or at least more interesting by cutting out blatantly weak sewing-together. If you do have a really interesting and convincing reason for these two sets of characters to be interacting (and you tell it well, as a part of the story not as an essay on spaceships or string theory), then I'll listen; if your explanation is more about cleverness than storytelling, I'd rather you skip pretending that you do and just get on with the story.

In light of which, my original post should probably have said "some people" rather than "people", but I seem to have been in the mood for a sweeping generalisation.

And two, in direct response to your example:

AJ Hall's Harry Potter/Vorkosigan crossovers don't really work for me for precisely this reason - I'm enjoying the characters' interactions, but I'm also frantically going "...but, but wtf? how? why? what? how?" and that gets in the way of enjoying the stories.

Those crossovers do work for me for precisely for this reason. I didn't have time to get bored with the sewing-together or setup. She took me straight into characters (who were, when I first read them, from a totally unknown universe) and made me interested in them. If she'd spent ten pages, maybe even two pages, telling me all about how they got there, I probably would have stopped reading, even AJ Hall's usually sparkling prose.

From that, I conclude that it's a matter of taste. I'm glad you were here to represent another point of view.
