The sequel is
Valley of the Shadow .
At one point there was a sequel to that planned but that was YEARS ago [though I did actually find part of it recently], but I think there's enough closure with VotS that it's not necessary like it was with FN.
Technically, FN is a sequel to Chris H's 'Baby I Hardly Knew You' which is no longer on the archive but is not necessary to read. There were a few minor changes to it and most of it is quoted in flashbacks so...
Carol [who went and reread the last para of FN and sees where James was coming from
