Ok guys I was in the enviable position of being a beta to the Big Bang Fic Adagio by Kimbari
Which can be read here, http://housebigbang.panfandom.ca/
And I can't recommend it more highly. It is the story of a love triangle between House, Cuddy and Julian a 30 year old ballet dancer who has the good sense to fall in love with Cuddy at first sight.
Seriously guys, excellent LONG work (30k words) and complete. I admit I'm biased, I tend to volunteer to beta for really excellent writers (which makes gushing about what they write easier) but I you'll love it. snark, sex, drama, dancing, sex, fighting, Jewish mothers, baby's... I cry (and laugh) every time I read it.
There are 14 other excellent fics at the archive to be read and enjoyed (and I'm looking forward to all of them, but no time to read and rec all tonight) and there are another 13 from last year so if you are looking for long fics of all descriptions this is very entertaining archive.
