The Prince in the Dream

First fic! (Excuse my semi-horrible summary) Elsa meets a man named Jack on the night of Anna's wedding. But something odd happens, leaving Elsa to wonder if the white-haired prince is real. Why does he seem to appear to the Snow Queen in strange situations? Where is he from? What is he hiding? [MAJOR JACK x ELSA] More characters to come! Possible other ships! Rated T to be safe!
