rivkat wrote me an awesome BtVS/SPN crossover for Sweet Charity - It's here (http://rivkat.livejournal.com/186951.html).

Oooh, I think I've read this one - but a long time ago. I shall have to re-read it, thanks for the link!

angelsdee wrote a long ass fic called The Killing Grounds crossing into Angel/BtVS/ and believe it or not The Fast and The Furious characters. It was a great mix! You can find it here (http://angelsdee.livejournal.com/57720.html).

Thanks, it sounds interesting, I'll be sure to check it out!

Rock On!

Thanks very much, that's awesome!

You're very welcome! I hope you enjoy it.

When you say slash, does that mean Wincest is okay? Because

There's an awesome turning-out-to-be-a-series of fics by kali1967 where Sam and Dean live in the Firefly universe.

And, in the same series, with BtVS

yep, Wincest is fine! Thanks so much for the recs :)

I'm a little bit of an xover junkie so I thought I'd help you out (and, thus, myself). Since BtVS and Firefly got quite a bit of coverage already, here are some for the other fandoms.

HOLY CRAP. Can I, like, give you my first born? THANKS SO MUCH.

(on a purely self-interested note, I see you have my own crossover on there. hee!)

I'll settle for cash. Kids are just too much work. ;)

(on a purely self-interested note, I see you have my own crossover on there. hee!) *Slaps forehead* Oops. Well, I have one of mine too so I guess it balances out.

Oh, yeah - I read yours. I really really loved it!

I can definitely recommend several SPN/BtVS crossovers by virtualpersonal. Here is the link to her SPN/BtVS crossover listing with links.

http://www.livejournal.com/tools/memories.bml?user=virtualpersonal&keyword=Fic+-+Crossover+SPN+%26+BtVS&filter=all

I can vouch for An Unholy Union and its sequel When Darkness Falls which feature Spike as the crossover character.

There is also several other interesting pairings including Buffy and some of the other scoobies.

Check out my memories for a few crossovers.
