I seldom read GenX stories nowadays, so these are all (well, mostly anyway) old stories I'm recommending. If someone would like to do a new stories rec, I'd be happy to archive it here, or provide a link to it.
Perfection Guaranteed. Scroll down until you find 'Understanding Monet'. Read them all. Keep in mind that these were written before the whole Penance/Twins/Monet mess. Appreciate the stories. Tell Maelstrom that you do.
Civics Lesson by J L Puckett is a classic and rightfully so. It's a highly entertaining read. If you haven't read it before I recommend you go do so at once.
Of Tuesdays and Two in the Morning by Hexadecimal and Nightfall is funny, sweet and good read.
To the Gallows Foot and After by Melissa is a nice little story exploring the friendship between Wolverine and Jubilee. [part 2] [part 3] [part 4] [part 5] [part 6]
Check out In the Midnight Hour and In the Light of Day by the same author for some Emma/Sean romance.
You might want to have a look at the The Second Chances series by Mandy 'Harlequin' Lever as well.
Well this is what I've got for now. Might end up updating this should I ever find the Danger Grotto again, or bother to read new GenX stories coming through OTL.
