Contrariety by
theebee (WiP, humor/romance, R, H/D)
A little rough around the edges, but I cannot resist quidditch fics, and this one seems quite promising.
Summary: During an International Quidditch Workshop at Durmstrang, Hogwarts’ favourite Seekers are forced to spend some quality time together. Featuring: Muggle arts studies, Patrick Swayze lovin', and, of course, H/D.
Quote: That was entirely uncalled for, Harry thought. Malfoy was just trying to draw attention to himself by being overly affectionate. He was probably trying to make the girls jealous, that prat. No normal person was that demonstrative with his friends. Harry didn't wander around kissing Hermione and Ginny and flopping ostentatiously around on their thighs. People just don't do that sort of thing in public.
Just one chapter up on Fiction Alley, but
ff.net has two chapters up.
