The fic ends when Thor's year is up and he goes back to Asgard. I think it was part of a series, but I don't think anymore of the series had been written (at the time that I read it).
I know that this fic is not Wild Ambition Fortune's Ice Prefers by amberfox17.
I'm 90% sure that I read it on AO3, but it might have been on lj.
I'd be so grateful if someone knows what fic this is and if they can tell me what happened to it or where I could find it! Thanks.
