Either Annabeth or Nico. Love those characters, so one of them would be nice. There could be a possibility that it would be Annabeth because of the name of the next book, "The Mark of Athena." I haven't finished "The Son of Neptune" yet though, so I wouldn't know if there was no way it could be either of them.
