A Demonic Day in New York by Hannah HasSpareTime reviews
Sam and Dean get wind of a great deal of supernatural activity in New York. While investigating, they run into some of our favorite Shadowhunters (and a sparkly warlock). Also, since this takes place in the present (2014), our beloved Shadowhunters are 6 years older than they were at the end of CoHF (just something to keep in mind). Rated T for slight sexual content and some gore.
