From a Tumblr prompt. Fat Amy sets Beca up on a blind date. Full prompt in end notes.

Elsa never meant to return to Arendelle. But the death of her father and a mysterious letter takes her back to the cold, forlorn city she once called home. She finds the once-proud city in its death throes, gripped by fear and intrigue, its magic in decay. And in the midst of it all, a strange young woman named Anna, whom everyone blames, but is she truly at fault?
