(Oz/ Alias)
Cat and Mouse by sistersleep
Sark/Keller - Does anyone really need a reason to read Sark/Keller? If you're the hard sell, know that this story is all kinds of hot. Keller gets a little more than he bargained for from a casual encounter, but he's hardly complaining. It's twisted and scary and wrong - YES!

(Alias/The Shield)
Thinner Lines by Jennifer-Oksana
(Multiple pairings but not the focus of the fic) Vic and Jack in the same fic and they manage to not kill each other! It's amazing! I don't think there's been a crossover this potentially fraught with egos since Judge Dredd met Batman. Uncannily like an episode of Alias (maybe not so much like The Shield but who cares, Vic is so... *Vic*). The tension builds convincingly and the non-linear flow of time makes you work just that little bit harder to stay on top of the story - and it's always more satisfying that way.

(Firefly/ST:TNG)
Serenterprise-D by Samantha
Absolutely HILARIOUS Firefly/ST:TNG crossover. Brilliant, and damn funny.

(From the Mixed-Up Files of Mrs. Basil E. Frankweiler/The Young Unicorns)
Marble into Music by Glossolalia
Brilliant, touching Emily Gregory/Claudia Kincaid fic, as told by Mrs. Basil E. Frankweiler. Full of dry humor with love shining through beneath, this story perfectly captures both Claudia and Emily, and the pairing just makes so much *sense*. I'm amazed no one ever thought of it before. *loves*

(Harry Potter/Sandman)
Incarnate by Fay Jay
Snape learns that stoppering Death isn't exactly as easy as he'd always thought. Lovely, bittersweet and beautifully capturing both Snape and Death, this is a great crossover.

(Harry Potter/Sandman)
Place We'd Never Leave by Dre
Snape meets Despair. It's not pretty, but oh god, the story itself is *gorgeous*. And the *ending*. I never thought I'd find myself feeling sorry for Despair, but Dre manages it. And Snape...

(Discworld/Sandman)
Whose Names Are Death by Afrai
Brilliant, poignant, clever story in which Death of the Endless visits Death of Discworld.

(Discworld/Sandman)
Further Reflections by foreverdirt
Susan Sto-Helit and Death of the Endless meet, and find they have things in common. Just delightful. The voices are spot-on.

(HP/XMM)
Curiosities by Penknife
Tom Riddle meets Erik Lehnsherr. Utterly creepy in the best way.

(HP/Sandman)
Prelude by Nifra Idril
Tom Riddle pores over Roderick Burgess's journals on how to capture Death, as Alex Burgess tries to keep him entertained and away from the prisoner in the basement. Shivery goodness.

(Ultimate Spider-man/Ultimate X-Men)
Spray Evenly, Until Slightly Damp by Azurine
Peter Parker and Wolverine sounds like an insane idea, especially in Ultimate-verse, but Az brings both the hot and the funny here. Logan is hurt bad, Peter's hiding him, and the smell is going to get Peter in trouble. So what's a superhero to do? Give the man a bath, right? And if that leads to other...activities, well, it's not like Logan's going to remember...is he?

(Red Dwarf/Farscape)
Work experience by andraste
Rimmer in Ace-mode encounters Chiana and naturally gets screwed while saving her life. This is just how it would happen. And Chiana's comment about humans who want to save the galaxy is just so perfect.

(Farscape/Firefly)
Crosses and Naughts by Thea
Mal and Aeryn make for a great pairing in this story, both a little broken and lost. This story is gritty yet hopeful, with lovely characterizations, especially of Aeryn.

(Ultraviolet/BtVS/PotC)
Carousel by Mary Borsellino
An odd mixture of universes which works surprisingly well, with a good Dawn-voice, at ease in the more sombre world of Ultraviolet.

(X-Men/X-Files)
Given Up by Yahtzee63
A wonderful blend of the X-Men and X-Files universe. Scully's regret is beautifully rendered and her climatic conversation with Nightcrawler is perfectly done.

(Smallville/Sports Night)
Networking by shrift
This story comes with a warning: VERY HOT. Scalding. Great dialogue too (just so I can show I noticed more than the sex) and definitely bringing the Sorkin. And both characters were beautiful and flirty while still being completely them - which was just damn good fun to read. 

(Alias/Bridget Jones)
Jack Bristow at the Edge of Reason by Yahtzee
Talk about an unlikely pairing. It's a madcap adventure of Bridget and Jack Bristow that will make you laugh until you cry, with hilariously dead-on Bridget-voice.

(CSI/The West Wing)
Places People Live by The Stylus
Stuck in Vegas, CJ meets the enigmatic Catherine. A girl-slasher's delight written with complexity and depth.

The Art of Make Believe by Abaddon
Brilliant, subtle HP/BtVS crossover. Harry Potter is just an ordinary boy with a big imagination, until he gets sent to the guidance counselor.

Emotional Scar by Laura Smith
A heartbreaking and hot Remus/Giles fic set soon after Sirius is sent to Azkaban.

The End of the Beginning by Mariner
Giles and Ethan run into some magical folk in the summer of 1981, and get caught up in their struggle against a deadly enemy. Yes, a BtVS/HP crossover that actually works, taking into account the differences in metaphysics and tackling the question of how MWPP could have become so fractured, plus Ethan and Snape snark, Giles being Research Guy and a lovely version of James and Lily that made my heart ache all over again for their deaths.

Resenting Paris by shrift
This should come with a warning. Very, VERY hot. So hot the blood rushed to my head and turned my face pink. Krycek meats Weiss and shows us all why there should be a Krycek for all occasions.

Highwire by Vehemently
Sydney's disappeared, and Jack and Will show up in London on a lead. A delicious Alias/MI-5 (Spooks) vignette full of sharp character moments, with not a single wasted word.

The Waiting Room by Nestra
Death's not what Buffy expected. Excellent BtVS/Sandman crossover, that nails both first season Buffy and Death. It made me a little sniffly and still put a smile on my face.

Lovers and Dreamers by Amy
Smallville meets the Muppet Show. No, really. It works brilliantly. Sexy bald billionaire Lex Luthor has just purchased the ever-foundering Muppet Theatre, thus sending Kermit, Miss Piggy, head writer Chloe Sullivan, and stagehand Clark Kent into a tizzy. Piggy comes up with a Sekrit Plan that, of course, backfires, Lionel hangs out with Waldorf and Statler, and the jokes fly fast and furious.

Lovely by Martha
This is an imaginatively-conceived and tightly-written crossover gen fic, covering Stargate SG1 and The Sentinel, with a dash of the creepy, a pinch of the intriguing, and brimming with generous helpings of insightful character moments. The story actually made me seek out and watch The Sentinel, such were the skills with which Martha drew the characters of Jim and Blair.

One Big Happy Pantheon by K. A. Rose.
A chance encounter between the Antichrist and the last descendant of Jesus Christ has repercussions on several planes.  Fortunately, we have just the angels, demons, witches, witch-finders (retired) and fallen, Purgatory-bound (except on their lunch breaks) angels for the job.

You (and Her) by Michelle k.
A fantastic Brenda portrait and some credible interaction with Donna from the Wing. What really impresses me is the little voice in Brenda's head that questions every move she makes. Effective and intriguing.

Perfection by Nostalgia
Another bizarre little tale from Nostalgia. Seven encounters existentialism and the shortfalls of representation. Philosophical, believable and insightful - and such a pleasure to read. Nostalgia's stories are always a treat to come across.

Given Name by Azar
I don't know why anyone hasn't explored this idea before. *Of course* River would remind Spike of someone in his past. Great voice for both characters.

The Scarab by BK the irregular
This is an entertaining action/adventure story that seamlessly integrates the canon from both Buffy and Stargate, with witty dialogue and voices that are just *spot on* for every  single character. A grand rollicking fun.

Forgotten Girl by Mary Borsellino
Set post-Gift, about Dawn and what if the spell the monks put on her had an expiration date. Also, an unexpected crossover that made me happy.

Them Mean Ol', Low-Down Lando Calrissian Blues by Yahtzee
Absolutely hilarious WW/XF/SV/Angel crossover that must be read to be believed.

Donna, the Vampire Slayer, by Nomad
A witty cross-over between "The West Wing" and "Buffy the Vamprie Slayer" with dead-on Sorkinesque Donna and Josh voices. Tremendous fun.

Touch by Seema
A Voyager/TNG crossover with Janeway/Picard.  An intriguing post-Endgame story, with captain/captain sex.  Can’t go wrong.

Unless You're Us by Editrix
Buffy and Spock attend a self-help group for the formerly-deceased.  With deadpan humour, lovely dialogue and an oddly familiar group guru...

No Fury by FayJay
Victoria Hardwick meets a woman in a bar. Wishing ensues.  Smallville/Buffy

The Language that God Speaks by Liz Barr
A wonderful little Harry Potter/Sandman crossover that runs with Terry Pratchett's idea that "all libraries are one library," with great characterization of all parties, and a Hermione I really, really like.

Fairy Wings by Ellen M.
There really is something about challenges that brings out the most extraordinary writing. Ellen M. takes Reyes and Amy and brings them together in a way that is fantastic - in the truest sense of the word. The writing is lovely and Reyes is perfect.

Impress by Kelly Chambliss
This is a Janeway slash story written from the point of view of DS9's Kai Winn. I love the way Kelly captured Winn's insanity, this steadfast belief that everything she did was the will of the prophets. The story is so convincing - it made me think about a character I'd long forgotten. And Kelly's writing is always a treat.

Letonia and The Ties That Bind by Cherry Ice
I really liked the way Cherry wove Scully into the fabric of the X-Men's lives, and the use of Doggett is inspired. Two universes that really work well together.

Than Fade Away by Jemima
Jemima Pereira, Queen of AUs, turns her attention to post-"Endgame" Voyager meta-fic.  Spans the breadth of modern Trek, with several highly dubious relationships and more than a dash of snark.

Borderland by CobraGirl
A fascinating, well written Sandman/Smallville crossover, that nicely meshes the two universes.

Like Minds by Perri Smith
An Angel/Dead Zone crossover.  Two strangers meet in a bar, only to learn that they have far more things in common than they first realized. There's a certain quiet glow about this story. It lingers.
