Fic Title: In The Dark
Author: Kellie M. (email@example.com) & Julia B. K.
Link: http://www.mrks.org/~kellie/fic/tng/trek.htm (Look for the story title on this page and follow the instructions to reach the story. Bear with me, and the author. The story is over 15 years old and was originally published online in the days of Usenet... Trust me though! So totally worth it!)
Rating/Warning(s): NC-17 (there is also a PG-13 version available)
WIP?: No... but it is first in a series...
Why This Must Be Read: OMG! OK... so imagine Guinan on Earth in the 90's, incognito. She runs into Mulder and Scully and kinda helps them with one of their investigations... which happens to deal with someone being beheaded by a sword. That's where, Duncan MacLeod comes in, along with his Watcher, Joe. And Guinan and MacLeod sorta hook-up, but he doesn't know about her being from another galaxy and already being like really old. Then the story fast-forwards to the time that Guinan is on the Enterprise and she runs into Duncan again. And they hook-up, again. Seriously, what's not to love about that, especially if you were watching TV in the 90s? The writing is superb and the plot is awesome. It is an excellent story and a fan of any or all of these fandoms can enjoy it.
Be Warned: In the sequel (Into The Light), it strays into threesome territory when Methos joins the party. And in the third story (Daybreak), it goes totally slash for Duncan and Methos. I am not reccing these stories independently here, since they fall outside the realm of "het." But, if you are up for it, they are great in their own rights and wonderful continuations of this cracktastic, incredibly well-written saga. (Further Note: The third story is available in the same archive as the first two... even though it says it isn't on the link page above! Trust me!)
