I was lucky enough to get there in time to pick Highermagic's fic 'Tradition can go Screw Itself'
Title: Tradition Can Go Screw Itself
Word Count: ~27,100
Spoilers: None, it's AU.
Warnings: knotting, asshole!Castiel, chasing, arranged marriages, references to MPreg, attempted non-con (not Destiel and doesn't go far), toys, rimming and D/s.
Summary: Castiel is an Alpha in high school – star athlete, most wanted bachelor on the market, and a temper to give him a reputation and a half. Unfortunately, that reputation has managed to reach the one Omega he never thought would be his: the one that he had been matched with from birth and was destined to be mated to. So, faced with the one challenge he can't fight away, Castiel has to prove to Dean that he's willing and able to be a nice guy – can be what Dean wants in a mate. If only it were that easy.
