Mostly now my writing is in character or as close to canon as possible. I no longer care to read much OOC nor care to write OOC stories, (which sucks when you're writing a sequel to one that was OOC) and I find keeping in character in an AU to be challenging but worth the effort as an author. Yes, everyone has their own version and it may take authors some time to find their way to canon but it is definitely worth it.
Linking to long fics since I think that's what you're looking for: (All WIPS will be completed by June)

Credence ~ AU ~ Friendship Fic ~ Wip (http://galeandrandy.livejournal.com/207613.html)

The Rhapsody Series -Tenebrosity ~ Post Series ~ Brian, Justin & their family dealing with the aftermath of a tragedy that happened to them three years ago (http://galeandrandy.livejournal.com/207685.html)

For short fics any at my master list except (Point of View and Ardor are In character)
GaleandRandy Master Fiction Index (http://galeandrandy.livejournal.com/166158.html)

I wish I hadn't already read everything on the list and I know there are some more not mentioned and I was going to post the ones I have categorized on my kindle but it's not working. :( IC fics seem to be in too short of supply over the course of BJfic, I guess that's why I'm so determined now to produce it.

Enjoy all your reading,
Rory
