College AU. When Alec gets his hands on an invitation to a Christmas masquerade party being hosted by Magnus Bane he sees it as his one chance to get close to the guy he's been crushing on for months now while disguised. And after all, how hard can it be to be someone else for a few hours and then slip away, no one ever knowing it was him?

Alec Lightwood was a no-good, dirty, rotten criminal. He was he leader of a drug cartel, making millions off of others' vices. The type of guy that any sensible mother would steer her children away from. And Magnus was a do-gooder, a trustworthy, law-abiding cop at the NYPD. They were enemies; so why did it feel so right in each others arms?
