Here are my bookmarks. Only two of them are not Loki-centric. http://archiveofourown.org/users/CatalenaMara/bookmarks
I also highly rec the following:
I do solemnly swear by Mikkeneko Summary: In which our heroes learn the perils of lack of inter-team communication, and Loki gives his side of the story. http://archiveofourown.org/works/518534
Road to Nowhere by Lise (Gen) Summary: When Loki turns up demanding Thor's help on a quest to retrieve the All-Mother from Valhalla, Thor isn't about to say no. But that doesn't mean he's forgotten anything, and what better time than a road trip through the backwaters of the universe for trying to talk things out? http://archiveofourown.org/works/1155790
Take the Long Way Home by cavaleira (Thorki) Summary: Thor strikes a deal with Loki: each month, he will trade half of his golden apple for one day spent together in a temporary truce. Both brothers find themselves getting more than they bargained for. http://archiveofourown.org/works/470291
Banished by Muriel_Perun (Thorki) Summary: After the Chitauri War, Odin sentences Loki to exile as a human on Midgard, in the city of New York, where he runs afoul of the Avengers again. Tony Stark makes Loki his personal project. But is exile enough to make Loki change? Or would Loki rather die than adapt to his situation? http://archiveofourown.org/works/1998348
