Well, one of the best known, and pretty damn close to IC series of fics I know of is "Children, Wake Up," by hollycomb on Ao3. You may have already read it, it's so good, and it's a 288,509 word MONSTER that is still being added to on a regular basis! https://archiveofourown.org/series/386986
There is also "all that you love will be carried away" by byzantienne and coldhope. Another series I quite enjoy, and also active. It is again on Ao3, and it's popular so may not be new to anyone. http://archiveofourown.org/series/396736
"Wayward Son" by ProfDrLachfinger is an incomplete standalone fic so far, but it's a good one. It's worth a read, though it's not as close to canon as the others, I feel. http://archiveofourown.org/works/5834020
That's all I've got right now, but if I remember any others, I'll be back!
